Sam lives in New York. His father has a shop there. His mother is a doctor. He is seven years old and he goes to school from Monday to Friday. The school is far away from his home. His father drives him to school every day. His teachers all like him because he is a lovely boy.

It is Monday morning. Miss Green teaches them numbers from one to ten. Sam studies hard. Soon, he can count them. Miss Green is happy and asks, "How many people are there in your family, Sam?" Sam stands up and says, "Two, Miss Green." "Huh?" Miss Green is surprised. She says, "There are three people in your family." "But now I am not at home. I'm at school."
