Lily is a good girl. She always listens to her parents' words and she never makes her own choice, but as she becomes a middle school student, she realizes that she has grown up and wants to make her own decision. This is the very classic situation for most children who wants to be independent, but they dare not to say out their inner voice, because they are afraid of hurting their parents' feelings. In fact, we need to speak out our voice and let our parents realize we have grown up. They will be happy and let us make our own decision. We need to grow up sooner or later.
