I've tried to answer that question more times than I can remember. It hasn't always been worded exactly that way, there are several variations, all of which are equally difficult to answer succinctly, which is what most people are looking for.
Recently a friend used an analogy that I think might help to explain why it's so difficult to sum up my life here to people who don't live here:
It's like living in an upside down house: everything is exactly the same, but it's so different.
Maybe that doesn't make any sense either. Oh well, I give up.
