Even when he is being stubborn, he is polite.
We were out taking an evening walk.
Pop: Well, I'm about ready to turn around and go back home. You?
Me: That is a great idea, Pop. Let's do it!
We turned around and headed back home and then a few moments later...
Pop: Well, I'm about ready to go back home. You?
Me: We are headed home, Pop. We'll start seeing it up ahead of us in a few minutes.
Pop: Nope. We need to turn around. It is behind us.
Me: See those trees up yonder? Our house is right behind 'em.
Pop: Well, I know who is wrong and I know who is right. And I'm right.
He was too polite even to tell me "You are wrong." I was thankful that I was walking a bit ahead of him otherwise he'd have seen the huge smile on my face.
