A policy implemented on the 6th floor of Deutsch Hall my sophomore year. The residents were very friendly and neighborly, and would usually leave doors open and/or unlocked. Problems started coming about when everybody on the floor (except me) starting to hook up with their neighbors. This led to many an awkward "Oops!" when waltzing through open doors. The solution I proposed, which was accepted by general consensus at a floor meeting: Go ahead and satisfy your urges with the nearest acceptable floormate, but for the love of us all, CTFD!" I think some of those to whom it did not apply anyway came away from the meeting not understanding the acronym for Close The Door.
