I am such a fucking idiot. I flew back to Tucson tonight, and of course they lost my luggage, and of course I left my keys in one of my checked bags. My flight got in on time at 2:30 am, so I didn't ask anyone to pick me up, was just planning to take a cab. It's way too early to bother my landlord to let me in my place, though. So, I guess i'm just going to camp here in the airport for a few hours. Lesson learned.
