<p>It's a good thing the whole situation seems to have blown over, but I'd be wary of writing an anonymous letter to one of your teachers. On more than one occasion, several of my teachers, especially the ones who teach writing intensive classes such as English or AP histories, have been passing back graded papers and come across one without a name. He or she would say something like, "You didn't have your name on it, but it just sounded like you." If the teacher has been exposed to your writing style, he/she may be able to pick it out of a lineup.</p>
