Finding out a bunch your group of friends from school still hang out and go on holiday together (9 years after you left)
It's a bit of a weird thing 'cos you see these people you used to hang out with and obviously you're not there and not invited (in my case probably 'cos I've neither called, emailed or made any other attempt to contact any of them for well over two years, decided I couldn't be arsed to go to two of their stag dos and basically have made no effort to contact them) but you end up torn between feeling oddly left out and nostalgic and thinking "why haven't these people moved on with their lives?"
Anyway, at what age did you stop hanging out with your gang of friends from school? Do they still hang out together without you?
