I'm single and I think that the whole dark hair, blue eye thing is really hot. But it doesn't really matter to me. All that matters is that they're not stuck up and that they are active somehow (sports, musically) that kind of thing.
Oh and I agree with the poster, English accents are the best. I want to move to London when I graduate college (a long time from now) and start a life there. I just love everything about Europe. And I want to experience it all.
Also, very awesome topic! haha :)
