Band Sub = Hetic Class = Pissed Of Me

OH MY GOD! I can't believe class today! We had a sub and he didn't know what he was doing. My friend and I were goofing off with the epic keyboard we have. It can make a buch of diffrent sounds and apperatly we were too loud so the fricking trumpet starts bitching. She comes in and slams the door marches over the the Keyboard and slams the the volume down and rips the fucking cords out of the amp. She starts swearing up a storm. Which just pisses me off. Of course I just finished an exam that was really stressful and so I am still stressed about that. Then the sub deicdes to play the peice of music I only have on eighth rest in (Imma Bass Clarinet xD) and so we start to play... The sub messes up the timing so we start again and we finish they decide they are going to play it again and and then I say Im not playing so everyone else decides they aren't playing and then we get into another argument. Then the somoker gets pissed and walks out >< now we are a clarinet short. I decide that if they don't shut up and play im leaving and then I leave cuz they wont shut the hell up. I finally go back beacuse period ends and I have to put away my instrument.. All in all First two blocks. Good... Third? Stressful... Fourth? Like hell come to band class...
