I suddenly felt like this recently when one of my friends organised a fancy dress thing and I realised that when I was a student I'd have put lots of effort into it but that I have so little time now, that just being able to see those friends felt like a luxury.

Even though I'm better off financially now, it's much more expensive to have a social life, partly because of distances but also because it pretty much necessitates going to restaurants and pubs, rather than sitting around in someone's room. I don't feel better off financially which is silly. I think I'd notice if I went back to living on a student budget though!
