I've always been fascinated by different people's accents. I think my family might have something to do with this - I have a grandmother from the south coast, Scottish grandfather, Dad from the industrial midlands, step-Dad from inner-city London - and then when I left home, I moved from the east midlands to Yorkshire. I don't sound like a "local" anywhere that I go any more, as my own accent and idioms are such a mish-mash of elements from all of those.
I also have a habit of picking up bits of other people's accents once I've been talking to them for a while. It's even got me into trouble when I've been accused of mocking the way people speak, even though it is completely innocent, and I don't even notice myself doing it until someone points it out.
The "Celtic" accents are my favourites, Welsh particularly, though I couldn't say why exactly.
