I'm in an apartment that seems borrowed; I'm living there while my friend is out of town or something, and I think I'm leaving later that day, and picking up my friend at the airport.

I'm surprised to run into this Asian fellow in the apartment. I ask him what he's doing there, and he says "what, you don't recognize me?". I apparently met him a couple of weeks ago, when we made the initial apartment exchange, and I took him to the airport or something. He explains that he's just a few hours early due to the way the flights worked out.

That gives me a few hours before I leave to shop for souvenirs for people back home.
