Many years ago，when I was fresh out of school and working in Denver，I was driving to my parents’ home in Missouri for Christmas. I stopped at a gas station(加油站) about 50 miles from Oklahoma City，where I was planning to stop and visit a friend. While I was standing in line at the cash register(收款台)，I said hello to an older couple who were also paying for gas.

I took off，but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend’s. We chatted on the way into the city，and when I got out of the car，the husband gave me his business card.

I wrote him and his wife a thank­you note for helping me. Soon afterward，I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful.

Years later，I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I’d left the lights on all day，and the battery(电池) was dead. Then I noticed that the Friendly Ford dealership—a shop selling cars—was right next door. I walked over and found two salesmen in the showroom.

“Just how friendly is Friendly Ford？” I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment，so when I got home，I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you，and it meant a lot，he said.

“Thank you” — two powerful words. They’re easy to say and mean so much.

     Jean is a bright young woman who comes from a rich and famous family. She goes to a good university

and has everything that money can buy. Well, almost everything. The problem is that the people in Jean's

family are so busy that they can hardly find time to be with her. In fact, Jean is quite lonely.

     So Jean spends a lot of time on her QQ. She likes being anonymous (匿名), talking to people who do not

know about her famous family and her rich life. She uses the name Linda on QQ and has made a lot of friends

whom she keeps in touch with quite often.

     Last year Jean made a very special friend on QQ. His name was David and lived in San Francisco. David

was full of stories and jokes. He and Jean had a common interest in rock music and modern dance. So it always

took them hours to talk happily on QQ and sometimes they even forgot their time. Of course, they wanted to

know more about each other. David sent her a picture of himself: He was a tall, good-looking young man with

a big, happy smile. As time went by, they became good friends and often sent cards and small things to each

other.

     When Jean's father told her that he was going on a business trip to San Francisco, she asked him to let her

go with him so that she could give David a surprise for his birthday. She would take him the latest DVD of

their favourite rock singer. But when she knocked on David's door in San Francisco, she found that her special

friend was only a ten-year-old boy named Jim!
