Dear Mom,

       I don't think you understand my life. You think I should be studying all the time. I know you want me to

find a good job when I grow up, but I would like to have a good time, too. You never think about fun things for

me to do like music and sports. Two days ago, when I was watching a football game on TV, you asked me to

stop and do my homework. After finishing my homework, still I wasn't allowed (允许) to read my football

magazines. You said I had to go to bed early. That was bad enough, but yesterday was the worst day. I bought

some music CDs, and put them in my bag so that you wouldn't see them. I told you I had to do my homework

first. I know it was wrong to lie (说谎) to you, but you told me that Dad would talk to me later. Mom, I didn't

quite like what you did to me! I really love you, Mom, but I hope you won't be so hard on me.

                                                                                                                      Love,

                                                                                                                      David
