yankeegirl, my boyfriend does the same thing. He wants to be called English not British.
My boyfriend comes and stays with me here in the states for a few months at a time. One of the things he cant stand is how Americans always assume that if you're from England, you must be from London.
The funniest thing happened the other day. This is his first summer here in the states, and we were walking through the park one warm night last week, when he suddenly got this TERRIFIED look on his face and pointing, asked me, "What on earth is THAT?!?"
I look to where he is pointing, and don't see anything but some grass. He says, "All those flashing lights, what are they?" I realize he is seeing the lightning bugs (fireflies), and that he had never seen them before. He was even further amazed when I actually went and caught one, explaining there is rarely a kid in the states who doesnt spend at least one night in the summer catching them. Needless to say, it was really funny. Makes me realize the things I take for granted, I never would have given the "flashing lights" a second thought!
