When someone had trouble saying goodbye and getting out the door, after he left my mother would say, "He obviously doesn't know the seven points of departure." I never knew where it came from until recently. My sister sent me a copy of a Reader's Digest article from 1933 (condensed from Atlantic Monthly same year) called, "The Seven Points of Departure." It is a humorous list of points starting with, "First stand up," and goes on until one is out the door. Anyone else heard this expression?
