It sounds like a parallel dimension to me! Is this what 6th form in London is all about or is it a private school thing? Suits? Detention? Calling your parents to see whether you're lying? At my run of the mill 6th form we all wore disastrous grungy hair, Cure T shirts and a miserable demeanour. Also used to get stoned before class and find any reason at all to be somewhere else doing something else... Never did me any harm (not true - life could have been so different).
Haha! Now that sounds like college
