I read a book/short story when I was in high school and I am wondering what the name of it is now. The story takes place in an all boys school and these two boys become friends. They play sports together and are the best of friends. At the end of the story the one boy kills the other boy by hitting him in the head, or he falls off a tree or he drowns or something. I think my imagination is running wild. Anyway please let me know if you know the author or title.

It sounds like A Separate Peace by John Knowles.
