Here's one of the interesting things about America: a stolid North Easterner like myself, even pre-living-in-Scotland-for-a decade, would feel as out of place in Nashville as yourself. Perhaps it is the pervasiveness of our popular culture, or it might have something to do with the relative paucity of our regional accents (I know, I know: we have screeds of them and some of them are barely intelligible to the uninitiated, but by and large you have to venture pretty far into alien territory to hear one of those, whereas in Glasgow I have to walk for about 20 minutes or go 1 train stop before I can't understand the local Maryhillish), but it's easy to forget how large a country America is and how diverse its culture. South of New England, I've often been taken for Irish (we share similar 'r' pronunciation habits, as in, we pronounce them) and may as well be from the other side of the planet as far as those from Maryland or Virginia are concerned.

America is a fascinating place. I hope you'll get to see more of it without having the misfortune of being stuck there ever.
