There's a plywood walkway from the rear deck of our rented house to the garage. Saturday night, while letting the dogs out, while barefoot, I stepped into the raised head of one of the nails that (sort of) holds the plywood down. The pain was truly remarkable. I bent the rim of our copper firebowl with my hands. The head of the nail tore into the side of the pad of my foot below my 4th and 5th toes. I may never go barefoot again.
