The motion-sensor light in the backyard came on a while ago, and now I'm all freaked out. Especially because not long after, one of the snakes decided to have a hissy-fit. A neighbor's dog sporadically barks, one of the behind-us neighbors motion-sensor lights was also on... I hate this prickly feeling. Start hearing things click off the windows, the roof creaks, the a/c makes the house thump. Crap.
