I say things are quiet and then things happen. I had to open the wife's store today because she needed to go to a big town and pick up needed merchandise. The store opens at 11:00 am so I was there at 10:30 am. I unlocked the door and went in; before I could even turn on the lights I heard a very small child run flatfooted on our hardwood floors. The child ran the entire length of the store. I turned on the lights and there was noone in the store but me. It sounded like a child because young children tend to run flat footed and make a slapping noise as they go. Someone suggest that maybe it was a mouse. I suppose it could have been if the mouse weighed 20 or thirty pounds, wore hard soled shoes and ran flatfooted. Somehow I doubt it.
