Families Work! Ellen Yung had a busy day at work! She put a cast on a broken arm, used a bandage to cover a deep cut, and helped twenty patients. Ellen is a doctor for children. Customers can get sick at any time, so pediatricians work long hours. They have hard jobs. Ellen's husband works long hours, too. Steve is a firefighter. At the fire house, he makes sure the tools work properly. He checks the hoses and fire trucks. At the fire, Steve rescues people from hot flames and smoke. The firefighters all work together to put out the fire. At home, the Yung family works together too. Hanna sets the table for dinner. She also helps wash the dishes. Everyone has weekly chores. Mom and Hanna do the dusting and mopping. Dad and her brother, Zac, do the laundry. They wash, dry, and fold the clothes. Mom makes a shopping list each week. She lists items they need and things they want. A short time ago, Zac wanted a new laptop. The family needed a new washing machine. They could only spend money on one item. Both cost the same. They had to choose. Clean clothes are needed for school and work. A new laptop is nice, but did Zac need it? Ellen and Steve thought about their family's needs. They decided to buy the washing machine. Zac knows that his parents have busy jobs. They bring home money to pay for their needs and wants. They needed that washing machine. Zac still wants a laptop.
