I've lived with five women. The first wore underpants for security. The second wore nothing. The third wore long nightgowns because they made her feel sexy. The fourth wore everything she could get away with because she was cold all the time. The fifth wears nothing.

My question is, why do so many people think anything that a man or a woman does means they are representatives of the entire gender, or that there is any reasoning for their actions that applies across the board?
