Dear Kate,
Thank you for your letter! I was really glad to get it. You're lucky that you don't have a uniform 'cause I don't find it very comfortable.
Also I've got lots of good and helpful friends at my school. We usually spend time at school together and we're trying to help each other with homework. My favourite subjects are Maths and P.E. Maths is rather interesting and P.E. involves running and playing volleyball. I like it. In our school everyone should wear a uniform and as I said I can tell that I don't really like it. But some my friends like it. Also some people just don't care about wearing it.
I'm sorry, but I need to go now. Hope you'll get my letter soon!
With best wishes,
