Whew, lots of finger pointing in this thread!
Right now I think I have lights on in 4 rooms. And I'm home alone. Shame on me. I'm lazy and don't like to mow my grass, so I pay someone to do it every week. I leave food in the refrigerator for too long and have to throw a lot of it out.
DH chews. That is money out the window. He also is guilty of keeping lights on throughout the house.
