The Tire Swing

Back when I lived in Shermerville a long time ago, there was a huge willow tree in the yard.
My dad hung a tire swing from it, and we’d swing on that.
When the knot would come loose, the tire would fall and roll and bounce around.
If you were inside it, well, you got knocked around with it.
After a few times that happened, instead of making the knot safer, the rope and tire were removed
Sometimes, I think back to that tire swing.
Then I look around at the world, and I realize, the knot is coming loose.
