I pick up thumb-tacks in the street and put them in my pocket. Some I use to stick up times on the corkboard, some I put back in the desk. Once a tack stuck straight through the ball of my foot as I ran straight on it, the ball of the foot came down, the heel lifted off pushing the ball of the foot down full on the tack. Running off I stepped off pulling off blind--leg, hip, spine, neck and tongue like a crack of lightning. If you want to keep time straight, you pick up tacks and put them in your pocket. —from "Thumbtacks, Glass, Pennies"
