I read your magazine every month.     1     我自己也是一个青少年, and have some problems at home that I hope you can help me with.     2     The main problem is that I can't get along with my father. Whenever I want to do something or suggest an idea, such as a restaurant we can go to for dinner, he doesn't listen to me. Then, when I refuse to listen to him, he shouts at me angrily.     3     He and my mother always make me do things I don't like, such as playing the piano and doing housework. Then, whenever I have some spare time and want to be alone, they call me selfish and distant!     4     如果我放外国音乐，我父亲很烦。Also, every time I watch a DVD: he sends me to bed or tells me to spend more time studying. He even forbids me from chatting with my friends in the Internet cafe!     5     I love him a lot, but I don't understand why he is so hard on me and will not respect the things I want to do. He was once a teenager—he should understand me better than he does.
