The role of a tutor is to offer the student helpful advice. And, like the adage goes, "you can lead a horse to water, but you can't make it drink." You sound annoyed that this student changed your revisions back to her original essay. That is par for the course where tutoring is concerned. To insult the student as "thin-skinned," and to insult her again, "should learn from someone who is a better writer and just improve her writing skills," makes me question why you ever wanted to become a teacher to begin with, if you despise students so much?

I think you should reconsider a career in education and choose another field. You don't come across empathetic or supportive (to me) but moreso insulting and patronizing. I've done tutoring with college students, and I don't take it personally when they revert to their original essay after I have provided them with my revision suggestions. It is the student's paper. If they don't like my suggestions, that is FINE with me. All I can do -- and all you can do -- is offer your suggestions to the students that you tutor, and accept the fact that they may not use all, but just some of your revision suggestions.

I really don't get a sense that you like working with students. That could be because you are still angry about being fired from your teaching job. But it's no reason to take it out on this student. That's how your post comes across. That you're taking out your anger on your situation, on her, because she rejects all of your revision suggestions as opposed to some of it. And, your reaction is to write insulting things about this student which is a totally separate situation.

The only advice I have for you, is to reconsider your line of work and possibly work with adults in a corporate environment instead of a classroom. If you don't like students (K-12, community college), then you should not be in a classroom as a teacher. There's just no point.
