My flippant answer is "Quite well!" But then I usually follow that up by explaining that it's just like a two-person relationship times
The second most common question is "How do you sleep?"
And since there seems to be an interest, and I mentioned it in a meme-comment today, I thought I'd share.
At the moment, Greg is sleeping on the side nearest the window, which is where the fan is, because he's a furnace and will overheat otherwise. I'm on the other side, Robb is in the middle, and Jerry is in Japan. We each have our own set of covers. (Which is a good thing, since I don't think we have any blankets wide enough to span the Pacific.)
