I know too many people who take the whole "going native" thing a bit too seriously. Kinda sad to see, really. I mean, if you're an American in London, for god's sake don't adopt an accent! And if you're a yankee in the south, don't try to sound like a good ol' boy! (And no, I am not referring to any specific person here- I was just using a couple of examples.)
Oh, and FP!
