Me and my group of friends are quite weird, in that every single character flaw, every screw up, every tiny mistake gets jumped on and we get slaughtered for it. It's just the way we work. A cousin from the US came over and it took him a few days to realise that we don't actually hate each others guts, but really it's just our sense of humour and we get a great laugh.
I'm perfectly happy with this situation, nobody talks behind backs, nobody bitches, if anything has to be said it gets said. Absolutely nothing is off limits, and that's the way it should be.
