Homecoming Rules

So, the new rule at my school is that no one can "grind" at homecoming. I suppose that's a reasonable request but if we can't grind, why play music about grinding? It doesn't make sence to tell students that it's bad and then turn around and promote it by playing music about it for three hours. Also, keeping the lights on the whole night is completely unfair to those of us that don't "grind". Why not just kick certain people out? After all, we only get to experience high school once.
