But her family are so busy that they can hardly find time to be with her. 1 So she spends a lot of time on her QQ. She uses the name Linda on QQ and has made lots of friends. Last years Jane made a very special friend on QQ. 2 He and Jane were both interested in rock music. So it always took them hours to talk happily on QQ. Of course, they wanted to know more about each other. 3 He was a tall, good-looking young with a big, happy smile. As time went by, they became good friends. 4 Jane asked him to let her go with him so that she could give David a surprise for his birthday.
