'Consider this: two friends met after a long separation. After greetings and pleasentries, one asked the other how his wife was.
"She's fine, I guess. we got divorced a year ago."
"Oh," the surprised friend responded. "I'm sorry to hear that. What happened?"
"I guess you could chalk it up to irreconciliable differences," the divorced man explained.
A long pause added awkwardness to the moment as the inquiring friend puzzled over the phrase, one that he'd apparently never heard. He broke the silence with, "Irreconciliable differences? I thought that was the whole point of marriage!"'
