When there is a
sock on the
door knob, this serves as a
notification that the people inside this
room or
apartment are having
sex.
Most common in
roommate situations where the person you share the
house/
apartment/
dorm/etc with are having
sexual relations and request that they be left alone. A sock on the door knob makes a
quick and easy '
do not disturb' sign. It also may be used for a
reminder of some sort.
If you approach a room with a
sock on the
door knob (or possibily a
rubber band), please please please do not
knock or otherwise disturb the occupants. Please do not call the occupants on the phone. They obviously have something better to do than see you.
GO AWAY!
