Alright, Isti â hereâs a longer and more detailed English version of the Isaac Newton text, still written at a level thatâs accessible for Grade 4 students, but rich enough in information to meet PISA literacy expectations and EF A2-level vocabulary. Iâve kept sentences short, clear, and with explanations for new concepts so itâs easier for young learners to follow, while still including both famous facts and lesser-known stories. âž» Isaac Newton: The Man Who Changed the Way We See the World A Boy from a Small Village Isaac Newton was born on January 4, 1643, in Woolsthorpe, a small village in England. His life was not easy. His father died before he was born. When he was just a few months old, his mother remarried and left him to live with his grandmother. Isaac missed his parents, but he kept himself busy by making things and exploring the world around him. As a child, Isaac liked to build models and machines. He made a small windmill that could turn with the wind. He built a water clock that told the time by dripping water into a container. He even made a sundial â a clock that tells the time by using the shadow of the sun. đĄ Did you know? The sundial marks that Isaac carved as a boy can still be seen today on the wall of his old house. âž» School and Curiosity When Newton first went to school, he was not the top student. At first, he did not pay much attention in class. But one day, another boy teased him for not being smart. Newton decided to study hard to prove him wrong. Soon, he became the best in his class. Isaac loved asking questions. He wanted to know how and why things happened. He enjoyed watching the stars at night and thinking about how the world worked. âž» The Falling Apple and Gravity One of the most famous stories about Newton is the falling apple. One afternoon, Isaac sat in his motherâs garden and saw an apple drop from a tree. This made him think: âWhy does the apple fall straight down? Why doesnât it fly up into the sky?â From this question, Newton began to think about gravity â an invisible force that pulls objects toward each other. Gravity is what keeps our feet on the ground. Itâs also what keeps the Moon moving around the Earth and the planets moving around the Sun. đĄ Fun fact: The apple did not hit Newtonâs head. Thatâs just a story people made up later to make the tale more exciting. âž» Newtonâs Three Laws of Motion Newton studied movement and wrote three important rules: 1. Objects stay still or keep moving unless something makes them change. âą Example: A ball will not roll unless you push it. 2. The bigger the push, the bigger the movement. âą Example: If you kick a ball harder, it will go faster and farther. 3. Every action has an equal and opposite reaction. âą Example: When you jump off a boat, the boat moves backward as you move forward. These three laws are still used today to understand how cars, rockets, and even roller coasters work. âž» Discoveries in Light and Color Newton also studied light. He found that white light is not just one color â it is made of many colors. He used a glass prism to split sunlight into a rainbow. This helped scientists understand how colors work. âž» Inventions and New Ideas Newton made a special telescope that used mirrors instead of lenses. This type of telescope made images of planets and stars much clearer. It is still called the Newtonian telescope today. He also worked in mathematics and helped create a new type of math called calculus, which is used to study changes and movement. âž» Strange Experiments Newton was so curious that he sometimes tested ideas on himself. Once, he put a thin needle, called a bodkin, beside his eye to see how it would change his vision. It was very dangerous, but luckily he did not go blind. đĄ Did you know? Newton also studied alchemy â an old kind of science where people tried to turn metal into gold. He never succeeded, but it showed how wide his interests were. âž» Later Life and Work At the age of 27, Newton became a professor at Cambridge University. He later worked for the Royal Mint, making sure coins were made safely and stopping people from making fake money. He was very strict, and some criminals were sent to prison because of his work. Newton never married. He spent most of his life reading, writing, and doing experiments. âž» The End of His Life Isaac Newton died in 1727 at the age of 84. He was buried in Westminster Abbey, a famous place in London where great people of Britain are honored. His work changed the world forever. Even today, scientists, engineers, and students still use Newtonâs laws and ideas. đŹ Newton once said: âIf I have seen further, it is by standing on the shoulders of giants.â This means we can make new discoveries by learning from the work of others who came before us. give 10 questions to each passage with PISA literacy standard for kid 10 years, 1. Nikola Tesla: The Man Who Dreamed of Lightning Born: July 10, 1856 Died: January 7, 1943 When Nikola Tesla was a boy in Croatia, he saw a flash of lightning and asked his mother, âCan we catch the light?â That question never left him. As he grew older, Tesla became a brilliant inventor, especially fascinated by electricity. He believed in a future where energy could be sent wirelessly through the airâlike music through the radio! Tesla invented the alternating current (AC) system, which became the foundation of modern electricity. At the time, Thomas Edison promoted direct current (DC), and the two men had a fierce competition. Many laughed at Tesla's bold ideas, but he never gave up. He dreamed of wireless communication, flying machines, and even free energy for everyone. Though he died alone and poor, today the world honors his vision. Think About It: Why do you think people didnât believe Tesla at first? What can we learn from Teslaâs courage to dream big? 2. Charles Darwin: The Man Who Studied the Worldâs Weirdest Creatures Born: February 12, 1809 Died: April 19, 1882 When young Charles Darwin got on a ship called HMS Beagle, he didnât know he would change science forever. He sailed around the world for five years, collecting plants, animals, and fossils. On the GalĂĄpagos Islands, he noticed something curious: finches had different beaks depending on their island. Why? Darwinâs observations led him to write the theory of evolution by natural selection. It explained how animals adapt and survive. But his ideas shocked many people because they seemed to challenge religious beliefs. Despite the controversy, Darwin continued his work. His book On the Origin of Species changed how we see life on Earth. Think About It: Should scientists share their ideas even if they go against what others believe? How did traveling help Darwin make new discoveries? 3. Marie Curie: The Woman Who Glowed in the Dark Born: November 7, 1867 Died: July 4, 1934 Marie Curie was born in Poland at a time when girls were not allowed to study science. But that didnât stop her. She moved to France, worked day and night, and discovered radioactivity, a powerful energy hidden inside atoms. She and her husband, Pierre Curie, found two new elements: polonium and radium. She became the first woman to win a Nobel Prize, and the only person to win in two different sciences: physics and chemistry. Even when Pierre died in an accident, Marie continued their work. Her discoveries helped doctors treat cancerâbut working with radioactive materials also harmed her health. She died from radiation exposure, but her legacy lives on. Think About It: What challenges did Marie Curie face as a woman in science? Why is it important to balance discovery with safety? 4. Galileo Galilei: The Star Watcher Who Defied the Church Born: February 15, 1564 Died: January 8, 1642 Galileo loved looking at the stars. He built one of the first powerful telescopes and made stunning discoveries: mountains on the Moon, moons around Jupiter, and that the Earth orbits the Sunânot the other way around. This idea, called heliocentrism, went against the teachings of the Church. He was put on trial and forced to say he was wrong. But he wasnât. He spent his last years under house arrest, quietly writing. Today, Galileo is called the father of modern science for daring to question what others blindly believed. Think About It: Why do you think Galileo was punished for telling the truth? Should science always follow evidence, even if it goes against powerful beliefs? 5. Isaac Newton: The Man Who Asked âWhy?â When an Apple Fell Born: January 4, 1643 Died: March 31, 1727 One day, an apple fell from a tree, and Isaac Newton began to wonder: Why did it fall down, not sideways or up? This simple question led to his theory of gravity. Newton also invented calculus, described the laws of motion, and changed physics forever. But Newton wasnât just a geniusâhe was curious, quiet, and often worked alone. He believed everything in nature followed rules, and it was our job to discover them. Thanks to him, we understand how planets move, how rockets launch, and why you fall when you trip. Think About It: How did Newtonâs curiosity lead to great discoveries? Do you think working alone helped or hurt Newton? 6. Ada Lovelace: The First Computer Programmer Before Computers Existed Born: December 10, 1815 Died: November 27, 1852 Ada Lovelace was the daughter of the famous poet Lord Byron, but she didnât love poetryâshe loved numbers! At a time when girls were expected to sew, Ada studied mathematics. She met Charles Babbage, who designed an early computer called the Analytical Engine. Ada imagined the machine could do more than just mathâit could create music, art, and even write! She wrote what is now considered the first computer program, long before real computers were built. Think About It: How did Ada imagine something that didnât exist yet? Why do we call her a pioneer in technology? 7. Albert Einstein: The Man Who Brought Time and Space Together Born: March 14, 1879 Died: April 18, 1955 Albert Einstein wasnât always a good student. In fact, his teachers thought he was slow. But Einstein thought deeply. He asked big questions like, âWhat if you could ride a beam of light?â His theories of relativity changed how we see space, time, and gravity. He also warned the world about the dangers of nuclear weapons, even though his ideas helped create them. Einstein believed science should help people, not harm them. With his messy hair, kind smile, and brilliant mind, he remains a symbol of genius. Think About It: Can someone be bad in school but still be brilliant? Should scientists be responsible for how their inventions are used? 8. Pythagoras: The Musician Who Loved Math Born: Around 570 BC Died: Around 495 BC Long ago in ancient Greece, Pythagoras believed the universe followed numbers. He discovered the Pythagorean Theorem, a rule about triangles that helps us build houses, design computers, and navigate space. He also believed that music had math inside itâthat certain notes made perfect harmony because of mathematical ratios. Pythagoras started a secret school and taught his students to search for truth through numbers, shapes, and sound. Think About It: Why do you think Pythagoras saw math in everything? How does music relate to math? 9. Rosalind Franklin: The Woman Behind the DNA Discovery Born: July 25, 1920 Died: April 16, 1958 Rosalind Franklin loved looking closely at things. She used a special machine called X-ray crystallography to photograph molecules. One of her greatest photos, called Photo 51, showed the shape of DNA, the molecule that carries lifeâs instructions. But her work was taken without credit. Two men, Watson and Crick, used her photo to build their famous model of DNA and won the Nobel Prize. Rosalind died young and never knew how important her work became. Think About It: Why is it important to give credit in science? What can we learn from Rosalindâs quiet strength? 10. Carl Linnaeus: The Man Who Gave Names to Everything Born: May 23, 1707 Died: January 10, 1778 Have you ever wondered why a tiger is called Panthera tigris? Thatâs thanks to Carl Linnaeus, a Swedish scientist who created a way to name and organize every living thing. His system is still used today in biology. Linnaeus loved nature and spent his life collecting plants, animals, and even rocks. He believed that by organizing life, we could better understand it. Thanks to him, we now have a global âdictionary of nature.â Think About It: Why is it important to name and organize living things? How does order help us understand the world?

On 8 August 1967, five leaders â the Foreign Ministers of Indonesia, Malaysia, the Philippines, Singapore and Thailand â sat down together in the main hall of the Department of Foreign Affairs building in Bangkok, Thailand and signed a document. By virtue of that document, the Association of Southeast Asian Nations (ASEAN) was born. The five Foreign Ministers who signed it â Adam Malik of Indonesia, Narciso R. Ramos of the Philippines, Tun Abdul Razak of Malaysia, S. Rajaratnam of Singapore, and Thanat Khoman of Thailand â would subsequently be hailed as the Founding Fathers of probably the most successful inter-governmental organization in the developing world today. And the document that they signed would be known as the ASEAN Declaration. It was a short, simply-worded document containing just five articles. It declared the establishment of an Association for Regional Cooperation among the Countries of Southeast Asia to be known as the Association of Southeast Asian Nations (ASEAN) and spelled out the aims and purposes of that Association. These aims and purposes were about cooperation in the economic, social, cultural, technical, educational and other fields, and in the promotion of regional peace and stability through abiding respect for justice and the rule of law and adherence to the principles of the United Nations Charter. It stipulated that the Association would be open for participation by all States in the Southeast Asian region subscribing to its aims, principles and purposes. It proclaimed ASEAN as representing âthe collective will of the nations of Southeast Asia to bind themselves together in friendship and cooperation and, through joint efforts and sacrifices, secure for their peoples and for posterity the blessings of peace, freedom and prosperity.â It was while Thailand was brokering reconciliation among Indonesia, the Philippines and Malaysia over certain disputes that it dawned on the four countries that the moment for regional cooperation had come or the future of the region would remain uncertain. Recalls one of the two surviving protagonists of that historic process, Thanat Khoman of Thailand: âAt the banquet marking the reconciliation between the three disputants, I broached the idea of forming another organization for regional cooperation with Adam Malik. Malik agreed without hesitation but asked for time to talk with his government and also to normalize relations with Malaysia now that the confrontation was over. Meanwhile, the Thai Foreign Office prepared a draft charter of the new institution. Within a few months, everything was ready. I therefore invited the two former members of the Association for Southeast Asia (ASA), Malaysia and the Philippines, and Indonesia, a key member, to a meeting in Bangkok. In addition, Singapore sent S. Rajaratnam, then Foreign Minister, to see me about joining the new set-up. Although the new organization was planned to comprise only the ASA members plus Indonesia, Singaporeâs request was favorably considered.â And so in early August 1967, the five Foreign Ministers spent four days in the relative isolation of a beach resort in Bang Saen, a coastal town less than a hundred kilometers southeast of Bangkok. There they negotiated over that document in a decidedly informal manner which they would later delight in describing as âsports-shirt diplomacy.â Yet it was by no means an easy process: each man brought into the deliberations a historical and political perspective that had no resemblance to that of any of the others. But with goodwill and good humor, as often as they huddled at the negotiating table, they finessed their way through their differences as they lined up their shots on the golf course and traded wisecracks on one anotherâs game, a style of deliberation which would eventually become the ASEAN ministerial tradition. Now, with the rigors of negotiations and the informalities of Bang Saen behind them, with their signatures neatly attached to the ASEAN Declaration, also known as the Bangkok Declaration, it was time for some formalities. The first to speak was the Philippine Secretary of Foreign Affairs, Narciso Ramos, a one-time journalist and long-time legislator who had given up a chance to be Speaker of the Philippine Congress to serve as one of his countryâs first diplomats. He was then 66 years old and his only son, the future President Fidel V. Ramos, was serving with the Philippine Civic Action Group in embattled Vietnam. He recalled the tediousness of the negotiations that preceded the signing of the Declaration that âtruly taxed the goodwill, the imagination, the patience and understanding of the five participating Ministers.â That ASEAN was established at all in spite of these difficulties, he said, meant that its foundations had been solidly laid. And he impressed it on the audience of diplomats, officials and media people who had witnessed the signing ceremony that a great sense of urgency had prompted the Ministers to go through all that trouble. He spoke darkly of the forces that were arrayed against the survival of the countries of Southeast Asia in those uncertain and critical times. âThe fragmented economies of Southeast Asia,â he said, â(with) each country pursuing its own limited objectives and dissipating its meager resources in the overlapping or even conflicting endeavors of sister states carry the seeds of weakness in their incapacity for growth and their self-perpetuating dependence on the advanced, industrial nations. ASEAN, therefore, could marshal the still untapped potentials of this rich region through more substantial united action
Some Arctic Dinos Lived in Herds
By Sid Perkins
Just as interesting, however, is how this was discovered. Scientists didnât look at a single fossil bone.
Instead, they analyzed a large number of preserved footprints on a mountainside located toward the
southern end of central Alaska.
Anthony Fiorillo works at the Perot Museum of Nature and Science in Dallas, Texas. As a vertebrate
paleontologist, he studies the fossils of creatures with backbones. In 2007, he was part of a research
team exploring Denali National Park. âWe rounded the corner and there they were,â he recalls.
Thousands of footprints had been preserved in stone. âIt was amazing.â
Dinosaurs died out more than 65 million years ago (not
counting birds, their modern-day relatives). So, itâs a bit
surprising that scientists know so much about these
ancient creatures. Now, a new study reveals that a certain
type of duckbilled dinosaur lived in the Arctic year-round.
These animals also traveled in herds that included many
age groups, they find. The creatures even appear to have
gone through a âteenage growth spurt.â
Those tracks pepper a steep patch of exposed rock about twice as
long as a football field and up to 60 meters (roughly 200 feet) wide.
They sit at least 160 kilometers (100 miles) north of the Gulf of Alaska.
Between 69 million and 72 million years ago, that now-rocky material
was muddy sediment on a floodplain near a seacoast, Fiorillo explains.
The hadrosaurs walked across the squishy mud. Later, the footprints
they left turned to stone.
Previous studies suggested adult duckbills took care of their young,
says Fiorillo. The new evidence that these dinosaurs truly traveled in
herds with multiple age groups confirms that parents cared for their
young well beyond the time they left the nest, his team concludes. The
researchers published their findings June 30 in Geology.

EVIDENCE FOR HERDS O F DINOSAURS
Small meat-eating dinosaurs called theropods had left behind a few of the tracks that Fiorilloâs team
found in Denali. Birds had left some others. But the vast majority came from creatures called
hadrosaurs. These large plant-eating duckbilled dinosaurs had been quite common during the
Cretaceous Period. That helps explain one of their nicknames: âcattle of the Cretaceous.â
For the new study, the researchers focused only on the hadrosaur tracks. More than half of the
footprints were preserved so well that they had clear impressions of the skin on the dinosaursâ feet.
Most tracks had a similar level of preservation. That suggests all were probably left within a short
period. Other fossils in the nearby rocks, including insect burrows, suggest these hadrosaurs had left
their footprints during the summer. These are trace fossils â evidence of ancient life other than a
preserved carcass or bone.
At the time these dinosaurs lived, Fiorillio says, the average temperature in the warmest months was
between 10° and 12° Celsius (50° and 54° Fahrenheit). Thatâs about what conditions are like today
along the border between Canada and the lower 48 U.S. states, he notes.
The team measured a large sample of the duckbillsâ footprints. They fell into four distinct size ranges.
The largest tracks, presumably made by adults, measured about 64 centimeters (25 inches) across. The
smallest tracks, 8 centimeters (3 inches) wide, were likely left by young duckbills. They would have
been no more than a year old. Tracks of two other size groups were probably made by juveniles and
near-adults.
These data suggest the community of hadrosaurs included four different age groups.

THESE DINOSAURS DIDNâT MIGRATE
About 84 percent of the tracks sampled for the new study had been left by older hadrosaurs â adults or
near-adults. Roughly 13 percent came from the youngest members of the herd. And a mere 3 percent
came from herd members considered to be juveniles, says Fiorillo. The rarity of tracks by these tweens
suggests that the young of this species had a rapid growth spurt. If true, they would have spent relatively
little time at this vulnerable size â and therefore left very few tracks.
âWhatâs really neat is how many small tracks there are,â notes Anthony Martin. An ichnologist â or
expert in trace fossils â he works at Emory University in Atlanta, Ga.
Other scientists had analyzed fossil bones from duckbills. These studies had hinted that the equivalent of
adolescent hadrosaurs would have experienced growth spurts. But the new findings are âthe best
evidence that Iâve seen,â says Eric Snively. Heâs a vertebrate paleontologist at the University of Wisconsin-
La Crosse. âThis is a great study,â he adds, âand further evidence that juvenile hadrosaurs grew up in an
eye-blink.â
Also previously, researchers had proposed that Arctic dinosaurs migrated farther south for the winter.
Thatâs because even if the region was much warmer than it is today, nights in the high Arctic would have
been 24 hours long. So, with no sunshine for several months, Alaska would have had long periods of very
bleak, chilly weather.
But finding juveniles in the herd
strongly suggests that these
dinosaurs remained in the Arctic all
year. Thatâs because adolescents and
preadolescents wouldnât have had
the strength or stamina to make
those long treks, Fiorillo maintains.
Field work is often harsh. Paleontologists studying the dinosaur
footprints here on an Alaskan mountainside sometimes worked
in cold and fog.

The presence of very young dinosaurs might have been expected, he notes: If this were a nesting region,
the babies would have hatched sometime just before summer. And remember, thatâs when these tracks
were left. But that wouldnât explain the juveniles, he says.
The teamâs findings âsuggest that these dinosaurs were overwintering in Alaska somehow,â says Snively.
At the time, the average temperature in the region remained above freezing even during the winter, he
notes. But, he adds, âthis study raises interesting issues about how the dinosaurs could live in the region
when it was pretty dark for several months at a time.â
The following days are a jumble of gunfire, digging, gobbled food, soldiers running in and out of the forest in small groups, distant explosions, stray shells, bandaged heads and unexpected lulls. On the very first day, before dawn, I am ordered into one of the newly dug trenches. I huddle there, squeezing my magic buttons and singing songs to the dog. When the fighting stops, the dog disappears, but a new companion takes his place. A strange little soldier crawls along the trench toward me. âPrivate Sasha!â he cries. âIâve been looking for you all day long!â Heâs old, like a grandfather, a dedushka. He has a black patch over one eye, a tape measure around his neck and a row of pins threaded into his sleeve. Hanging from his belt is the most enormous pair of scissors I have ever seen and I wonder if he uses them as a weapon. He doesnât tell me his name, so in my head he becomes Dedushka. Dedushka squats, cups his hand to his ear, peers over the top of the trench and smiles. âItâs safe to be upright . . . for now.â He helps me to my feet, dusts me off and commands me to stand as tall and straight as I can. Then he measures me. Everything from head to toe â even my toes! He writes numbers in a little notebook, strings his tape measure back around his neck, salutes and hurries away. Itâs all very strange, and I wonder if Dedushka has been bumped on the head during the battle and is now a little bit muddled. I should have given him a hug before he left. I chase after him but stop when Iâm hit by a shovelful of flying dirt. Sleepy Bear is digging a cave! âAre you going to hibernate?â I ask. Sleepy Bear chuckles. âNo, although that would be wonderful! I could do with a lo-o-o-ong sleep.â He sighs and closes his eyes. He doesnât open them again and I realise that he has gone to sleep. Standing up! I shake his arm, and he opens his eyes and keeps talking. âNo, Iâm not hibernating. Iâm digging a little nook where I can sleep and eat. Iâll hang up my raincape as a door that can open and close so it feels just like a real home . . . except for the lice . . . and the bad smells . . . and the bombs that make the walls shake and crumble.â He points further along the trench to where other soldiers are digging. âWeâre all making little houses in the ground.â âLike rabbits and moles,â I say. Sleepy Bear chuckles. âYes! And soldiers who need to hide from German bullets and bombs.â He stops digging to roll a cigarette. âShould I be making a house?â I ask. âI want to hide from German bullets and bombs, too.â Sleepy Bear flops to the ground, lights his cigarette, closes his eyes and takes a deep puff. I wait for him to answer, but, instead, he begins to snore! I poke him in the side. He snorts and he murmurs, âI think someone has already built you a house, Sasha. Keep going along this beautiful village street and you are sure to find it.â He falls asleep once more. I kiss his dusty cheek and whisper, âThank you, Sleepy Bear.â A little way along, I see Cook in a cloud of smoke. He has lit a fire, right here in the middle of the trench, and is stirring a cauldron full of kasha. He squats as he stirs. âWhat are you doing?â I ask. âCooking supper, of course!â he cries. âBut why are you doing it here?â Cook points his spoon at the ground above the trenches. âBecause if I do it up there, my pot will be filled with holes from German bullets and all of the kasha will leak out onto the ground. Itâs bad enough that our supplies canât get through German lines and thereâs nothing to cook but buckwheat for kasha. But if we lost the kasha, too . . .â âHungry soldiers,â I say. Cook nods. âAnd grumpy!â âLike Boris!â I gasp. âEven worse,â warns Cook. I picture the kasha pot full of bullet holes. And then I realise that if the kasha pot were full of holes, then Cook would be, too. I wrap my arms around Cookâs neck and say, âI think this is a very good place for cooking our supper.â I kiss his smoky cheek and run along. At the end of the trench, I find the biggest hole of all. Itâs wide and deep and as busy as a beehive in a blossom tree. Above, a group of soldiers is rolling logs into place for a roof, while below, typewriters rattle and pencils scratch and papers flutter and voices crackle out of five different radios. Their words tangle together to tell a strange wartime fairy tale about German guns and a loving father called Stalin and a Red Army regiment that is lost in the deep, dark forest and a wicked beast called Hitler and a delivery of vegetables that was hit by a bomb and blown into a million tiny pieces too small even to make soup. In the middle of it all, wrestling with a rumpled map, his rifle still slung over his shoulder, is Major Scruff. âMajor Scruff!â I run and jump into his arms. âIs this our new home?â âYes, Sasha. I suppose it is.â âIs it safe from German bullets and bombs?â I ask. He stares at me. âWere you scared in the trenches today, Sasha?â âNo,â I reply. âI had magic buttons and a dog and some songs to sing. Were you scared in the forest, Major Scruff?â âYes,â he says. âPoor Major Scruff!â I press my hand against his cheek. The dark, rough stubble is grubby with grit and his eyelids are taking a long time to open after every blink. âYou need a shave and a nap!â I scold. He chuckles. âI am too tired to shave and too busy to nap.â I scrunch my nose while I consider his problem. âI know!â I cry. âYou nap and I will shave your whiskers. That will be two jobs tumbled into one!â And so thatâs what we do. Major Scruff slumps into a chair and snoozes while I lather his face with soapy water and shave his whiskers. The soap suds travel from his face, up into his hair and down the front of his uniform, and I have to shave his jaw and chin three times because I keep missing bits, but I finally get it all done. I am just wiping his cheeks dry when the dog appears. He licks my hand, then stretches up and licks soap suds from Major Scruffâs ear. Major Scruff wakes with a start. He feels his newly shaved face and cries, âWonderful, Sasha! I feel smooth, clean, rested and ready for action.â He ruffles my hair. âWe must do this again tomorrow. Although next time, you might wake me with a gentle shake of the shoulder instead of licking my ear.â
