When I took intro to sociology in college, my teacher told the class to conduct an experiment. He said we should knock on the door when we got home and ask to be let in. He told us to ask permission for everything we do, like using the bathroom, eating food, etc. He had a whole big list of things we were supposed to do to play with the minds of our families.

Next time the class met he asked us how the experiment went. I told him "pretty interesting seeing as how I live alone".

(There should be a law against sociologists... )
