I remember growing up and my parents telling my brothers and sisters and me to turn off unused lights in the house. In my effort to do my part to conserve energy, occasionally I have to remind my favorite Princess to turn off the unused lights in the house:
Me: P, are you done in chaos cave (her room)?
Me: Please turn the light off.
P: I didnt' turn it on.
Me: I turned it on so YOU can see while in YOUR room.
P: Well, it's YOUR house!
With that said, I turned off the light and returned to studying for my midterm.
