Erwin McDonall Told Me This Tale
That he hasn't hit anyone since the fourth grade. But towards the end of their marriage, he got so angry at his wife that he opened the hutch in the dining room, took out her grandmother's porcelain serving tray (the big one, the one you could put a turkey on), and smashed it to bits on the floor.
He had to do this, he said, to demonstrate to her how rotten he felt, in general.
The passionate moment passed, but these many years later the feeling of deepest regret still has not.
