In highschool, I was almost kicked out of marching band for being sick.
The band director was going crazy that year. He kicked a kid out during practice for not knowing the fight song which was the first time I'd ever seen him kick someone out in 4 years. He kicked my sister out for going to her school club (she was the president so she had to be there) instead of practice.
What happened to me was different. I have this weird ability to tell when I'm going to get sick. Its like this feeling in my nose of irritation days before I get really really sick. I told him on Wendesday that I might not be at the game Friday because I could feel myself getting sick so that he could prepare to cover my spot on the field up.
Friday comes and I got a call asking where I was. I told my friends I was too sick to perform. It was the middle of winter and my parents (who are both doctors) forbid me to go seeing how sick I was. Monday comes and....everyone was staring at me and whispering. The band director walks in shortly after me and in front of everyone sitting down prepared to practice he says:
"What are you doing here?"
"uhm...I'm here for practice .-."
"No you're not. You are no longer in this band. Get out"
I was so shocked I couldn't even argue I was so embarassed he was yelling at me. I went home crying and when my parents found out they raised hell! We had a meeting with the principal and the band director. They explained that they were both doctors and that I was way to sick to leave the house. They asked for a better explanation as to why I was kicked out because afterall you can't kick someone out for being sick. The band director kept saying things like "in the handbook it says she will be kicked out for missing performances no matter what" so my parents ask for the fucking handbook and he comes back showing us the school's code of conduct handbook that contained no such rules. I.e. there was no fucking handbook he just wanted to kick me out by bullshitting up some rule. The principal decided there was no reason for me to be kicked out and I went back to practice. It felt really good to come back and tell everyone how the meeting went and how humiliated he was that he didn't get his way. He continued trying to be a dick to me but I was flawless.
