There are a fair few Rahs at Newcastle. I came here from a Comprehensive in the Midlands, so I had never had any contact with Rahs whatsoever. But I find I get on with some Rahs, not with others; likewise, I get along just great with some non-Rahs, and not with others.
TBH, I think the whole "I can't get on with any Rahs whatsoever" is a pretty narrow view. Rahs can be stuck up and arrogant, but many of them are nice people - maybe a bit well-spoken, or they come from richer families, but there's no reason at all as to why you shouldn't get on with them
Unless of course, you go to Uni with the view "I will not get along with any rahs..." in which case you probably won't, but it won't be because of how they are.
