So often, one runs across trays in neighborhood convenience stores with pennies that are free to take. Sometimes, they are mass-made vacuum-formed boxes with “Take a Penny, Leave a Penny” stamped on the side. Even more often are handmade trays and homespun sentiments from the storeowner. When I need a penny, I don’t question what type of person left it or how I’m supposed to use it. In kind, I don’t leave a penny for only “certain” types of people to use. I delight that this smallest gesture, or economy of kindness, is entirely off the books.
