Too many people to quote, I don't really have a good reason for wanting to live there. I am just fascinated by what I see. I know it's a premature not thought out thing to say, but until I experience it, it's the greener grass on the other side of the fence for me.
As for the accent comment let me apologize for my ignorance on the topic. As an american I have an idea in my head of what a british accent is and I'm sure it's what most americans view as a british accent, and I honestly like out, again probably just because it's do different from what I'm used to. Irish accents come in a close second for me.
I meant no disrespect and fully admit I am uneducated in what I'm talking about, but those are my thoughts based on my experiences.
