the comment made by a teacher still makes me feel disgusted whenever I think of it

I have moved on from the comment my teacher once passed on me but sometimes when I think about it, I really feel how insecure I was made to feel only for not sitting like a girl?! yes, as a fat girl child it was hard for me to sit one leg over other in classroom or anywhere ( it is still) so, I used to sit with legs wide open, was this a problem or an issue this big that my teacher told this to my mother in a PTM and especially by calling her close and into her ears " that your daughter doesn't sit like a girl " I felt disgusted, it was disturbing as hell I used to sit uncomfortably whole time and especially in her period, I still can't believe that I was called out for being comfortable in my own classroom when I was just 9.

my close friend referred to me while playing dumb charades as an elephant only to say the letter "E", was it that hard for her to explain it in any other way I laughed it off so, that they don't think that I can't take it normally
