It depends on who you are, and who you're living with. Really, it does. I always seem to be in conflicts all the time, be it with one flatmate or another, whereas everyone else in the block tend to hang around with everyone else in the block. Me...well, I could safely say that, with no foreseeable problems, I've found mates for life within my seminars. But, if I'm not with them, then I'm either working (Rock City, woo!) or I'm with my friends in the Rock Society.
Which brings me onto another point...Joining a suitable society is a must! When I say suitable, I mean something that you're very passionate about, and will definitely stick to. Take my example, the Rock Society. I'm extremely passionate and opinionated about my rock and heavy metal music, so £5 was a small price to pay to be part of such a group. And it just so happened to be the society awarded last year as the best society within the Uni, and, if the national Rock Soc forums are anything to go by, we're also the most active Rock Soc in the country.
It doesn't matter what type of person you are, that is to say, it doesn't matter if you're shy or outgoing, whether you make friends easily or whether you find that something a little more challenging, because, if the Rock Soc's anything to go by, then people won't care about any of that stuff when you join a society. I tend to be the one who's happy enough to stand in the corner, watching in on everyone else. Unfortunately, that's what I did at the first Rock Soc meeting I went to. But it didn't matter, because others were in a similar position (surrounded by new people), and others had been in that position, so they just came up to talk anyway.
So, despite my ramblings, I guess what I'm trying to tell you is that, when you get here, read through the society booklet you're given, find one you'd really enjoy, and join it, because, despite how many times it might have been said before, and despite any clichés given with what I'm about to say, societies are probably the best way to make good friends outside of your seminar groups - that really can't be said enough times.
