I'd say I was laid back, easy going and for better or worse very much the "nice guy" type (despite a tendency for inappropriate and vulgar humour, in the right company of course!).
Naturally quite a quiet, self conscious and shy chap but whenever possible I do like a good laugh as it were (whether I have a good sense of humour I'd imagine is completely subjective). I very much feel I'd be lost without being able to laugh at myself, the world with all it's ills and random stupid silly nonsense.
I feel like I'm quite intelligent but I'm also definitely a right dopey get so I don't mind at all if others don't concur with that judgement.
I'm more or less always tired too :-)
Finally in terms of philosophy and ethics I'm very much a negative utilitarian but I don't really talk about it :-)
(That summary wasn't as brief as I'd hoped - sorry)
Summary aside I thought I'd just say that I'm on here basically to meet new people as I'm not meeting too many people otherwise. In an ideal world I'd find the love of my life sooner rather than later but in the real world I'll definitely settle for meeting a few nice new people, making friends and seeing what happens.
