The other day, my wife and I got into some petty argument. (I say it was petty. She would have said it was Armageddon.).
As it was, neither of us would admit the possibility that we might be in error.
My wife finally said, "Look. I'll tell you what. I'll admit I'm wrong if you admit I was right."
"Fine." I said.
She took a deep breath, looked me in the eye and said, "I'm wrong."
I grinned and replied, "You're right."
