Can you tell us about an unexpectedly involving conversation you got into?

I find that sometimes I get into deep conversations at, of all places, cocktail parties, or business meetings, or even after parties (after performances). Maybe you get into such conversations, too? It’s not always just chit chat?

Usually these discussions are about subjects I care about passionately, like health care, or art, psychology, parenting, education, lifting people out of poverty, peace, etc.

Have you gotten into an unexpected deep conversation lately? Where did it happen? What were the circumstances? What was it about? Give us the flavor of the conversation.
