She doesn't turn the lights off when she leaves a room. If I come home in the middle of the day, there's lights on all over the house and she's gone. I'm surprised we don't constantly blow fuses.
Also, she has low power lights and those little battery powered candles all over the place. The house is lit up all night. Some are at least on timers, some stay on 24/7.
I wondered why we bought batteries in bulk. Hell, I only use a couple a year. It's the damn candle lights!
I'm just the opposite. When I'm home alone, I turn off all that shit and walk around in the dark.
