AITA: FOR BEING PETTY AT MY FELLOW DANCER?

So, I am British. (Great start, huh?)

I do traditional British folk dances in either towns or villages. My role (when it isn't otherwise filled) is to be the "Dame" of the group - which is basically a cross-dresser. Anyway, I haven't been to dance in a while, due to many factors including college - so now and again, I falter and miss the odd step while we're performing.

And I have various conditions due to this, but the main point is that I have them and I don't want to dwell on mistakes when they happen. Luckily, that is the general consensus and we often get over mistakes that we make.

There have been occasions people would give me advice and I have overreacted to it; to the point of being dismissive. Even to the most experienced.

But there is ONE person in our group (who, by the way, is there much LESS than I am,) who doesn't only point them out - as I am accustomed to people reminding me the right steps - but sort of gloats about it. Very competitively.

So, I have, right off the bat, haven't been taking that attitude well - to the point I had told our dance leader of the situation. They have been impartial, but were glad to inform the person about my feelings of the situation.

I had told my mum about the situation - VERY blatantly during break; spewing things like, "I'm not taking his shit!" - and she had told me not to overreact or give him the oxygen. Fair enough.

As hours passed and dances continued, they didn't ONLY carry on, but crammed it into the GROUND. As I miss-stepped at one point, they remarked, "it's turn and spin. We have told you this time and time again."

One could argue it was construction criticism and I simply needed to remember that element of the dance, but that person has been getting my skin prior to the whole situation. But another part of me wonders whether it's simply insecurity about being a novice.

Am I the asshole for that?
