One is a flurry of unaccustomed politeness as the shiny new freshers still please-and-thank you, and squirm in obeisance when asking for directions to the cloakrooms, or help in solving their "treasure hunt" questions like "what does UDMS stand for?" or "what are the Library's opening hours?"
Another is the strange metamorphosis you see in students who'd been perfectly normal last year - who've suddenly been reborn as american cheerleaders, bouncing around trying to excite the freshers about the prospects of a year on this hallowed ground on intellectual endeavour.
And then there's the aesthetic assault. Whoever imagined that an O-Week Tshirt could be quite so, well, urgly? Eish! If one is going to offend the Ninja Turtles, why not do them all at once, rather than picking off just one of them for special discrimination?
If you find them offensive, please engage, via any of the avenues open to you. This is a University after all, a place which thrives on debate and encourages diversity of views as well as people.
And which resorts to censorship only as a very very last resort, for the truly incorrigible on whom flagellation no longer has the desired effect... ;)
