In my school the mens bathroom requires you to check out a key from the front office(which is only a few yards away), but the girls bathroom is unlocked. On the other hand, our bus driver makes all the girls sit past the back half of the bus.
Yeah it's loveiest, but it's merely the cold hard truth, most kids in teenager level, girls are more trustable, and I agree with that.
I think this might actually be a problem with schools, or at least mine, because honestly I've always noticed girls are always glorified by the teacher and if they're annoying then the teachers just laugh and play along. If a guy is annoying or dumb the teachers hate them. Everyone's catching on and it's getting weird.
