I am a final year undergrad student in mathematics. This is an important detail as usually there are not many mathematics students, and even less in their final (because of the dropout rate). Because of this, the number of students is pretty small, around 12-18, which allows the teachers to notice every one of us, learn our names, habits and etc.
Now, one of the Teacher Assistant seems to dislike me. One of the reasons for this is at the beginning of the semester I spoke too much according to him. I took this criticism with no problem, and made sure to talk as little as possible during the classes, that is I spoke only when a classmate would ask a question based on the problem we were working on. Yet, he still seems to be irritated by me. I once answered my friends question in a quiet way, to which my teacher responded: "you're such a pain". He likes to ask questions first to me, which no one is able to answer. In a situation where my answer was far from being right he responded: "you would better not answer than give such an idiotic answer". This isn't very detailed, and shows only my point of view, but I wish to fix this situation or at least improve it. I am unsure if this Stack Exchange is suitable for this question, in case it's not, I will delete my question.
Now, I would like to talk to him as I want to fix this situation and to do so I would like to first send an email asking to meet up. I want to know what exactly should I state in the email? I definitely don't want this to backfire me in any way.
So my question: how should I phrase my email to ask for a meeting to discuss this situation while staying polite and very tactiful?
I will accept any advices concerning the handling of this situation.
