Last night I was very proud of myself for going to bed early. Technically, it was actually this morning but still very early for me. At one-something I toddled off to read for a bit and then slept happily until some freakish hour in the obscene part of the morning when I awakened to a tick-tick-tick in my room, it sounded more mechanical than of animal origin. It was coming from my closet, where two chains hang down from the attic door. They were clinking together. I watched them clink, stopped them with my hand, then they clinked some more. I figured I'd check the attic later, with daylight and awakeness on my side, and I went back to sleep. But now I think I've figured it out without further exploration. Earthquake!
