Jean is a bright young lady who comes from a rich and famous family. She goes to a good university and has everything that money can buy. Well, almost everything is good. But the problem is that Jean’s family are so busy that they can hardly find time to be with her. 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 who 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 a picture of himself: He was a tall, good looking young man with 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 favorite rock singer. But when she knocked on David’s door in San Francisco, she found that her special friend was a twelve-year-old boy named Jim!
