As I was shoveling snow, this morning, I decided to clear the snow off of the Nissan. When I did, I found the note I had left on the Pontiac which was parked across the end of my drive, the other day.
I thought the guy had probably just thrown it away, but he wrote a reply on it and stuck it on my car.
It's hard to see in a scan (apparently his pen was short on ink), but at the bottom it says,
"I apologize 4 the inconvenience."
Quite all right, old chap. Just don't let it happen, again.
