But since last year she has become a little mysterious(神秘) and not as open as before. She wants heart-to-heart talks between mother and daughter. But they never happen. And a gulf(沟壑) opens between them. Her mother wonders if she falls in love, It's too early for a girl of her age. After all, she is reaching the "dangerous stage". These thoughts have caused trouble in the mother's mind.

One weekend her daughter came to tell her mother that she was going to the cinema with her classmates and would return late.
