Dear Peter,
　　Friday is a busy day for me. Let me tell you something about my school life. I have six classes on that day. I start class at eight and have four classes in the morning. In the afternoon, I have two classes. After class I play soccer ball with my friends.
　　My favorite subject is English because it is interesting. I don’t like math because it is too difficult for me. What’s your favorite subject?
　　What about your Friday? Can you tell me something about it?
Yours,
Li Lei
