What noise?

Been hard at work since the beginning of the year working on various home improvements. In January, we finished the ceiling and crown moulding in the kitchen, and this month we’re bound and determined to finish sanding the living room floor and polyurethane it. My mother had done the library/piano room on her own, so I do feel obliged to do the bulk of the living room. At first, the critters went scurrying away from the noise like they do from the vacuum cleaner. After a week of it, they can sleep right through.
