At school, I can’t wear the clothes I like. I can only wear the uniform. I don’t like the uniform. That makes all the students look the same. And I can’t even listen to music in the classroom. It’s unfair. I think listening to music helps us relax． At my home， there are also many rules. For example, I have to do a lot of homework. And I can’t watch TV or play computer games. I don’t think it’s a good idea. Because students need some time to have fun. It’s important． I want to know your rules. Write to me soon. 38 $$
