Leaving lights on...he knows better but he seems to think it's no big deal to leave lights on all the time. Yelling didn't work. So he's charge a dime a day he leaves them on.
Grounding doesn't work. Taking his light doesn't work he just leaves the bathroom light on to use, and frankly he needs a light for home work and music practice.
I have been doing this 3 months....he hardly leaves the light on.
