What's it for?
It feels important, almost necessary, especially in a debate, to make the final point. But of course, not everyone can have the last word. Someone needs to concede in order for the conversation to end. What happens if we choose to intentionally not have the last word? How does this affect the outcome of the conversation? Do we "lose"? Perhaps we gain more through silence than by winning the point. Maybe we get to extend our relationship further. Maybe we get to play again. And, isn't this the underlying purpose? Artful conversation, gaining insight, being wrong and learning are the game. And, it shouldn't need to end at the expense of being correct.
Consider the best last word might be actually be two...thank you.
