Try this for size: (it can be either emotional or physical) If someone behaved towards me the way I do to them, how would it feel?
Would I feel happy or sad, attraction or repulsion?
Just try it for an hour, a day, a week: turn the tables.
Robert Sanderson's XII sermons, 1634:
"Whosoever thou art that dost another wrong, do but turn the tables: imagine thy neighbour were now playing thy game, and thou his."
