    Jean is bright a 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 her time on QQ. She likes being anonymous (不知姓名的,名字不公开的), 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 contacts quite often.

    Last year Jean made a very special friend on QQ. His name was David and he 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 the 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 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 Jean knocked on David's door in San Francisco, she found that the

special friend she had written to was a twelve-year-old boy named Jim.
