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”

    My friend Mr. Smith is a famous doctor and has a hospital. So he has enough money to travel all over the world. And he's been to a lot of places of interest. He likes to play with children and has a lot of little friends. They often ask him to tell them all kinds of funny things he saw. It makes them happy and his room is always full of children when he's free.

    It was my little son's seventh birthday yesterday. The boy wanted to ask his old friend Mr. Smith to the party. He called Mr. Smith himself and told him about it. The doctor accepted his invitation happily.

    Mr. Smith came on time, with a nice present in his hand. After dinner the children sat around the traveler and asked him to tell them some funny stories. Mr. Smith agreed and his stories made them laugh again and again. At last he told them the funniest story. He said, “Once I reached a city on a foggy day. The fog was the thickest in the world…”

    “Please wait a moment, Mr. Smith,” said my son, “It's said that the fog in London is the thickest in the world.”

    “You're right, my clever boy.” said the funny doctor.” The city had much fog that day…” “What's it, then?” the boy couldn't wait to ask again.

    “The fog was so thick that I couldn't see it at all.” the funny doctor said with a smile.
