I'm reading the marching band article now.
Reminds me of how my music career came to an end in fifth grade. I had politely waited and waited and waited in the hall outside the music room until the kid who came before me was finished with his lesson. When he finally left, the music teacher refused to give me my lesson because "I was late" (when I was just being polite), and it was time for someone else's lesson. When I got home from school and told me mother what had happened, she phoned the school and got the music teacher on the line. I didn't listen to her end of the conversation--I don't know why--but I presume she ripped the music teacher a new one, and that was the end of my music lessons/music career.
