Tsk! Tsk! You assume my checking the fridge for the cat is rational behavior. Silly girl. I don't know what started that one, but boy was I tired for a few years.
Another one that drove my husband crazy was when we first got married, when I went to work, I brought every hot appliance I had used that morning to the car (blowdryer, coffeemaker, etc) just to make SURE I had shut them off and they wouldn't burn the house down.
Thank goodness I've gotten it under much better control, because it can make you crazy, lol!
