There doesn't have to be a dance for the police to show up at my school..
I'm not sure if you still have to have the permission slip signed or not to buy a ticket. Last year, a bunch of kids got drunk and came into the dance completely wasted, and as a result permission slips had to be signed. Those kids were never punished either, they got away with it. That pissed nearly everyone off at my school because they were the high and mighty popular kids. They were seniors, the big sports stars at my school, national honor society members, the kids my school puts on a pedestal to set an example for everyone. They were the kids held in high regards so when they were suddenly at the other end of the spectrum, the administration stepped back and did nothing and that's what pissed everyone off..
Oh well..
