When my children were little, one of my pet peeves was that they would not turn off the lights when they left a room. If it was dark and they were going upstairs to get something from their rooms, they would turn on the upstairs hall light; stop in and use the bathroom leaving the lights on; go to their room; grab what they needed and come back downstairs leaving their room, bathroom and hallway lights on. I always saw it as an unnecessary waste of energy and money lighting an area that did not need it. A compromise was achieved: I installed presence detectors. They had light when needed; I had lights turned off when not needed.
