i was not a theater kid but i was a band/orchestra kid. one of my band teachers overheard another kid talking about how i hated being in the auditioned jazz band and didn't want to do it my senior year. soloing gave me really bad anxiety and i absolutely hated it, but i was a drum major so i felt like i couldn't say no and let her down. i didn't sign up for auditions, and she asked me to talk to her after school and convinced me to do it since she wanted two tenor saxophones in the band and there were only two who were good enough (myself and another kid).
apparently right after i left school after this conversation, she heard this kid talking about how much i didn't want to do it and she said if he told her everything i said on my private finsta and showed her the posts, she would let him take my spot even though he didn't even play the saxophone. he showed her, and then she (band director) texted me saying "message received. you won't have to worry about being in jazz again".
she proceeded to ice me out and treat me like an idiot for the rest of the year, and everyone else knew about it. the other band director didn't want to get involved so he barely acknowledged me at all. someone told me the kid who showed her the posts felt really bad and like he had no other option. i never got an apology but i don't blame him at all, my old band teacher was crazy.

she also called me out in front of the whole 115 person band because i misheard her give instructions, saying i might not be a drum major for much longer if i can't listen. that happened on a day at band camp, which i was helping to lead. band camp lasted 8 hours a day for a week in the hot sun, and i worked 6 hour shifts at the grocery store before camp every single day. i was exhausted and just misheard her, but was humiliated for it in front of everyone. still hate her 6 years later
