My wife cleans whenever she gets stressed which I manage to cause for her on a regular basis.
Before my last surgery we had made arrangements with my parents to come help out with the kids, my wife and parents don't exactly get along. Her first thing to clean when stressed are the hardwood floors, Sweep then mop. I swear she wore the floors out in the weeks leading up to that event, she must have done those floors at least 5 times a day not to mention the bathrooms. She cleans those every couple of days, when stressed at least once a day sometimes more. Needless to say the house was sparkling by the time my parents arrived.
