"When there's a disagreement, it's me planting my feet and wanting to be right. And I am right. I am right from my perspective and from my current level of understanding. That's my truth in the moment, until I can understand where you're right also."

Two accurate accounts of the same event, built from two different sets of information and two different nervous systems. There is no evidence either person can produce that will dissolve the other person's experience. So the argument has no exit. It only has an exhaustion point.
