She is a cute, quiet girl. As a daughter, she has no secrets from her mother, who is very pleased with her. But recently she has become quite mysterious(神秘的), not so open as her. What if she falls in love, which is too early of her age? After all, she is reaching the "dangerous time". These thoughts have caused trouble in the mother's mind.

One weekend the girl came to tell her mother that she was going to the cinema with her schoolmate and would return late. This was the first time her mother agreed, and she couldn't help worrying because her daughter had never been away at night before. The mother waited till nine and decided to go out to meet her daughter. Just at that time the noise of a car pulling up drew her to the window and—there was her daughter, waving goodbye to a boy. Her heart missed a beat. When the girl came in, the mother was watching TV, pretending nothing had happened. "Mum. I'm back. " "Yeah." "Sorry to be late. Still sitting up? " "Yes. Oh, that. . . Who's that boy? "The daughter was stunned(发愣) for some time. "Ah. It's my monitor. He gave me a lift on his way home. Mum, I'm going to bed. " "All right. Go to sleep early. "

Next morning when the mother went to the daughter's room to do some tidying, she found her diary, left at her pillow(枕头). After a few minutes' hesitation(犹豫), she finally opened it to the page of last night. It says: Mum, it's love that made you ask, but it would show your understanding of me if you hadn't. Holding the diary, the mother feel in thought.
