With roommates, there are things they do that irritate you to no end. They don't know that they do it but you don't tell them because it's not that important in the scheme of things.

If the light is on and no one is in the room, then we are wasting electricity which equals to wasting money. Not to mention our light bulbs will burn out faster.
Bottom Line: Turn off the lights.
