Emma: Hello, Timmy. Who is that man? Timmy: That is Curtis. Curtis plays football for the local team. He is my favorite player. Emma: I think that he is short. What do you think? Timmy: No, he's not. Most football players are tall. It helps them to catch the ball. Emma: Is Curtis very strong? Timmy: Yes, I think that he is strong. He can also run fast. That is why he is good at football. Emma: I see. Are you strong? Timmy: No, I'm not! I'm not good at football like Curtis. I am not strong or fast.
