Because you look like a guy who we would like to have living in one of our cupboards. We met him today and he was unusually, exceptionally nice, in addition to having messy hair and being unshaved in a very attractive way. He had to borrow our library card to print something, and maybe that was the only explanation to his civil behaviour . He then introduced himself to our other friend by saying that we are like yin and yang. In his world, that means that we are opposing forces who will never get along.
In our world it means that we complement each other in perfect harmony.
