Actually, I've lived all over the place throughout my live, so I have heard that quite often. To me, it still seems best to introduce us by what we want to be called, and clear up any confusion if they ask or seem confused. (granted, i'm in utah now so i haven't had to do that in a while )
That's interesting. I've never heard of anyone doing that before. That seems similar to what I used to do, just the other way around.
