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 wonderful time, too. You never think

about fun things for me to do like music, 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 couldn't 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 computer games, and put them in my bag so that you wouldn't see them. I told you I

had to do my homework first. I knew it was wrong to lie to you, but Mom, I didn't quite like what you

did to me! I really love you, Mom, but I wish you could try not to be so hard on me.

Love ,

Zhang Ning
