I don't have a black hole. I have a ghost. I "lost" my 1"X6" ruler from my upstairs sewing room. It re-appeared months later in the silverware drawer in my downstairs kitchen which I am in every single day. I have no kids, no pets, and my partner avoids my sewing room like the plague. It's the ghost. The same one that turns on lights downstairs when I am alone in the house. It's the ghost.
