ok well im not a teacher but i do know as i was a student not long ago most of us treat casual teachers like crap coz we know we can get away with a lot more without the usual teacher around not sure how u should deal with it maybe if it gets unbareable u should talk to a coordinator or vice principal or even the principal as boys can be a lot worse when it comes to playing up at skool i know its not very helpful but it is an insight into students world i know im guilty of doing it sometimes i wish i didnt but cant take it back now
