Have you ever played the boardgame "Sorry!"?
Today as I was observing my cousins-in-law playing the game I noticed the glee, mischief, and ultimate gloating that would occur every time a "Sorry!" card was picked. There's no better way to say you're sorry than to mockingly take someone else's gamepiece and move it back to their start.
And once, there were two "Sorry" cards in a row. Let me tell you, the best revenge for one sorry is your opponent picking up another sorry and screaming it with triumphant delight.
I think I took note because of those times when my apologies are uttered from selfish motives. Often times I'll give or forgive with my own self-interest in mind.
Funny what a kids game can teach you about yourself.
