For the first time ever, I broke a guitar string. Well, technically, the change in temperature and humidity broke it because I wasn't actually touching it at the time, but I think having played on it quite a bit prepared matters. It scared the crap out of Julie and me, occupied with quiet activities. Julie, of course, maintains that it was a ghost or something supernatural since the cat often seems to be seeing things. I'm going with physics.
Same with the streaks of blood on the wall.
