Dear Dave,

I’m not happy. There are too many rules in my house. It isn’t fair. I have to get up at five o’clock every morning. I can’t arrive late for school. I have to be there at eight o’clock. I have to come back home after school because I have to do my homework. In the evening I can’t watch TV because I have to help my mother make dinner and wash the dishes. I have to go to bed before ten o’clock. On weekends, I have to stay at home on Saturday morning. I have to clean my room and wash my clothes by eleven o’clock. On Saturday afternoon, I have to go to the children’s palace to learn the piano. Do you have lots of rules? Are they fair?                                                                   

Your friend,

Alice
