Massachusetts. I haven't lived there since 1996 but when somebody asks me where I'm from I never
say Atlanta. Instead I say, "I live
in Atlanta" or "I live
in Georgia." With or without the italics. Inevitably people rephrase the question as "No, where are you really from?" (And if I then say Massachusetts, half the people then rephrase with "No, before that
!" and go on to tell me they know I must be from Germany, because it is so
obvious to them.) But seriously, I really do consider Massachusetts my home, in my heart. That influence is ingrained very deeply into me.
Now for practical purpose, home is the condo in Downtown Atlanta where I've lived for seven years now. And I've lived in that same neighborhood for ten years. That is "home" in a practical sense. When I see chewed up fried chicken carcasses, smell homeless people and hear squealing buses, I know I'm home. And yeah, when I have people saying hi to me and calling me by my name every half a block, see pretty early 20th century buildings and encounter dogs who know how to use elevators, I know I'm home too.
