This happens to me every time I've been to visit the land where I grew up (Japan). For a long time, I called it "home," and I refused to acknowledge that maybe it was time to call my current residence "home." But eventually, after living here longer than any other place I've lived, I reluctantly decided it was time. I still do get homesick though, and sometimes imagine that my whole family has disappeared and that I am free to return "home." Sigh...
