I go out with people who don't give a damn about awkwardness generally. We talk about all sorts of crap though, it depends. Philosophy especially when drunk for some reason, Does God exist and if so is he a bastard? Football, beer, jobs, I don't think I've ever thought about it it just happens, but then I never run out of things to talk about meself.
In case your wondering the general consensus on God was: no shut and get a round. And if he does then of course he's a bastard now go and get a round, respectively.
