I rang the doorbell and was greeted by a beautiful black and white Cocker Spaniel. Soon thereafter, the dog's human showed up. He was an older man, quizzical and friendly. He was pleasantly surprised to find out we were there to make sure he was okay. That we'd seen the door open. He was fine. He was just getting a cross breeze going. We said our good-byes and went on our way.
I've been thinking about the small event, our concern, and the man's surprise over the whole thing. It was the right thing to do and, I think, he was shocked that strangers would come check up on him. There's a lesson in all this but I haven't figured it out yet.
