Aha! That's an easy one - because I get bored very easily and find it impossible to settle. I'm the worst kind of commitment-phobe - I can't commit to a place to live, let alone people or jobs or activites. So I have to keep moving. I think it comes from being an Army brat, even though I was too young to remember most of the moving around back then - what I mean is, I was never a 'local' where I grew up. Despite being born in Gloucester, twenty generations of my family hadn't lived in the Forest of Dean previous to my birth and my mother's Irish, so we weren't integrated in the local villages the way most of the other kids' families were. I never thought of it as home, so now, when I move around, its impossible to feel integrated in any of these temporary places either and I don't like any of them enough to settle down and put down roots. That'll happen in America I think, or maybe London. Or Europe, but its not likely to be England outside of the capital.

There. Much more information than you ever needed or wanted, I'm sure.
