Another thing is why, Cass is a cunt, and so was Debbie, Rachel has her body issues, Priti is sexually repressed, and Amy is always late, what exactly have we seen that Lucy needs to be punished for, other than her doing to strip tease behind what's her face, the student president, Lucy really at least unless Altos has a secret hidden naughtiness like she is the pothead, Lucy is pretty much a perfect student, again I freely admit my bias, but what is naughty about her.
