A dog shadow puppet doesn’t really look like a dog. But you can look up a table of “shadow puppets,” and there it is, labeled with the word “dog.” That word could also mean friend. Or feet. Or a hot dog, which is different than a hot dog. And a hot dog is different than a hot dog. Which is different than a dog in heat. Maybe a sandwich, an animal with a temperature, a sexy animal, or the same, just at a particular time in its life. Whatever “it” is, it’s always elsewhere, running away, one step ahead.
