I saw one show in the middle of the road, so I moved it to the curb. I walked a bit further and found the other shoe on the side of the road. When I came back through the second shoe was still there, so I carried it to back to be reunited with the first. No clue if their owner ever found them. They must have been on someone’s car and fell off at different times. Both were near curves in the road.
Did you reuntie them, too?
