The only thing that bothers me about the band - is when you meet someone thats in the band and all they can talk about is how awesome band is or how crazy band parties are.
I am a former band member and proud of it. There are some that live for marching/pep band and think it's the greatest thing on earth. Then there is the other at least 90% that are there for something they enjoy doing and the lifetime friendships and memories. I am sorry you met the diehards and think they are losers, some would probably say the same about some people that all they do is live for sports.
Oh and band parties used to be pretty crazy but since there is no longer a "band house" there aren't all that many from what I am told.
