On the dank and dirty ground, you see a shiny penny. You pick it up. You turn it over and over in your hand. You’ve heard stories about these copper discs, how they were once used to buy things like candy and newspapers. Your father was once standing on a crowded subway platform and he looked up, smiling, thinking of a funny video he’d seen earlier that day, shared with him by you, of all people, and someone else on that crowded subway platform had decided to throw a penny in the air, and it hit your father right on his left front tooth and that tooth chipped, the small bony piece flying up and then down, never to be seen again. You love your father’s strange tooth, now mended, but the shadow of the crack visible in bright light.
