What Is Home?

I'm at the point in my stay in England where I forget that I'm somewhere besides home. Just now, I was talking to someone online and they brought up that I am, in fact, here. My reaction was, "Oh, yeah... I am, aren't I?"

I can't decide if this is good or just really really sad, since I leave in less than a month.

It's interesting how people, places, and routines become such a part of your life that you forgot you knew oherwise. It's startling to remember that it's not what you've always known, and even more startling to know that it's going to be gone eventually, and perhaps for good.
