When my brother taught health in a school in Eastern Canada they promote a dumb idea that we should sleep with our windows open. A kid in the class was troubled because he slept with his uncle and his uncle wasn't going to keep the window open in freezing Canadian winters.

Then one day the kid tells my brother that he slept with the window open the night before. My brother asks the kid how he was able to pull it off. The kid answers, "My father was away so my uncle slept with my mother."
