Every time they left the room unattended. We'd run a fucking mUCK!! I mean... set off fire alarms & use the powder in the room. Shit would get damaged. People would fight. The board would be COVERED in graffiti. The goths would do their goth stuff. The nerds trying to be goody-two-shoes wouldn't get a word in from the shouting. The hot chicks would up and leave to the toilets to smoke their cigarettes. Stoners would just blaze up right there in the room. The fat chicks would just stare forward unless they got spit-balled. The "foreign" students would leave to head-office. The footy-jocks would... I dunno what they'd do, I never payed attention... The clock would get changed quick-smart. Some people would just up & leave. If it was tech, some would make weapons. I personally would just leave with 3-5 crew and invade the music room to have a jam on the instruments. I was at my school the very first day the place opened.... I wasn't even enrolled properly at the start, so I was bounced to 3 classes the very first 2 hours there! As the school was brand new, it took literally 2 years for the teachers to have disciplined students. School man.... it was a blast! Good times!
