Do you ever see a shoe lying abandoned in some random location, and wonder how the shoe got there, and what befell the other shoe in the pair?
I have seen two such shoes recently.
The first was a woman's shoe, stuck in the mud at the bottom of a puddle on the edge of a parking lot. American Toads had laid eggs in the puddle a few weeks earlier; if you look closely, you can see a tadpole swimming around inside the shoe.
The second was an old red sneaker. It floated upside down in a backwater pool of a rocky stream, absolutely motionless, forming an odd vista of cosmic peace and harmony.
