Fred is eight years old. He goes to school near his home. He always goes there and comes home on foot. One day he comes home from school late. His mother sees him and asks him, "Why are you late, Fred?"

    "My teacher is very angry and asks you to go to her office tomorrow."

    "To her office? Why?" his mother asks. "Because she asks a question in the class." Says Fred. "Nobody can answer it, but I can."

    "You are so clever, my son." His mother says with a smile.

    Her question is "Who puts the tomato on my chair and makes my trousers dirty?" says Fred.

    Every evening at six o'clock an old man goes to a restaurant near his house. He eats dinner. After dinner, he drinks coffee and talks to the people at the restaurant.

    The old man's name is Bill. Bill eats at the restaurant every evening because he is lonely. His wife died and he has no children.

    Every evening the same waitress(女服务员)brings Bill to his dinner. Her name is Cara. She is 17 years old. Cara is kind to Bill. She knows he is lonely, so she talks to him. If Bill is late for dinner, she calls him on the telephone. “Are you OK?” she asks him.

    One evening Bill doesn't come to the restaurant. Cara calls him, but he doesn't answer the phone. Cara calls the police. “Please go to Bill's house.” Cara tells the police. Later the police call Cara at the restaurant. “Bill died in his sleep,” the police tell her. Bill was 82 years old.

    A week later, a man comes to the restaurant. “I have something for Cara,” the man says. The man gives Cara a check(支票) for $500000. The money is from Bill.

“This money is for me? From Bill?” Cara asks the man.

    “Yes,” the man answers.

    “But…why?” Cara asks the man.

    “Bill liked you,” the man says. “You were kind to him”
