I'm sitting here alone in the house and thinking about something that happened several months ago. (Probably because I just read the new book by the Ghost Hunters.)I was on the computer and our daughter's dog started yapping in the kitchen. He kept it up for several minutes and finally I went in there. A huge bag of cereal was very slowly being pushed out of the cupboard. I watched, openmouthed, as it inched its way out and finally fell. The dog started running around the room in a circle, looking up and yapping happily, as if he were chasing Peeves the Poltergeist around the ceiling.
I leapt up and looked in the cabinet to see if a cat or anything (please! let us have a mouse just this once!) could have pushed it but there was nothing there. I picked up the bag to see if maybe a string was tied to it, although I was alone, but no. The thing is that only about a fourth of the bag was hanging over the edge when I first saw it moving out. It didn't fall until gravity pulled it down..it had to have been pushed or pulled in some way.
