If I didn’t already know what a potato was, I could easily mistake this object for a rock. On closer inspection, however, it becomes easier to tell that what I’m looking at is, or was, alive. One clue is that it has clearly grown: there are wrinkles in its surface, which you would not normally find on a rock this size. Next to those wrinkles are small divots, and, inside each divot, the light red color that covers the object in patches grows darker, suggesting that pigmentation is gathered in those spots. Again, this is not something you would see on a rock, rigidly structured. Even the brown color is not uniform. Small spots of green and yellow are scattered throughout. And, as I said yesterday, it has some give to it. When I squeeze, the skin bends, ever so slightly. I push my thumbnail through the surface. The skin splits with the sound of a boot stepping into wet grass.
