That's a good point, one I often wonder about. When will I stop feeling like an American living in Canada and begin feeling Canada is my home? How long after moving? Will it ever happen? If I live in Canada for the rest of my life, and I'm lucky enough to have a long life, it should.
More importantly, when will I stop feeling like a New Yorker? That's an identity I wear pride, as opposed to my apologetic feelings about being American.
