Power tools

Dad has got to quit all this power tool business. He seems to think now that he's in a house he gets to use his toys again. Well, this silliness has got to stop. I'm losing weight tearing from room to room to get away from the noises he's making. Last night it was the power sander ... dust everywhere and noise like you wouldn't believe! Why doesn't he go outside and cut the grass if he wants to make noise?
