Sandy, I have to tell you something that'd been pestering me this past weekend. Out of nowhere during Saturday afternoon, I suddenly had a mental image of a mouse hole. First it was inside the house, then it was outside, under the house, then it was inside again. Now, keep in mind that I had severe insomnia and had only slept for 3 hours, so it might just be my brain going haywire -- but the images kept coming back and each time I'd see a little more, but somewhat fuzzy images.
One particular mental image of the mouse hole was by a radiator, against a very white wall.
