As an expat this is not an idle question. Most expat contracts include a plane ticket "home" about once a year. Where people choose to go is ineresting. I recently had lunch with an American colleague whose parents moved away from the US many years ago and are living in Dubai. Her significant other (boyfriend) is in England. She doesn't really know where she'll go for home leave.
I was always surprised when adults of my age group would ask whether I was going "home" for the holidays. I answered "no, I am home; I'm going to visit my parents in Michigan."
When I relocated to Ethiopia I sold my house in North Carolina, so I don't really have a "home" there. But all my friends (who serve as my extended family) are still there, so it feels like home. Pretty much. My parents both live in Michigan, where I grew up, but I left on purpose in the 90's and Michigan doesn't feel like home. Of course my parents being there make it home-like when I visit.
