Don't you know how hard it is for some people to get out of a room after their visit is really over? They want to be off, and you want to have them off, but they don't know how to manage it. One would think they had been built in your parlor or study, and were waiting to be launched.
-- Oliver Wendell Holmes (The Autocrat of the Breakfast Table, 1891, p. 17)
Mark's note: Some sermons are like that. I recently told a young preacher in training: "You should have only ONE "in conclusion" -- not two or three. If you don't know how to land the plane, it's much better to turn off the engine and crash land, than just circle until you run out of gas."
