Get worked up about a swimming pool. When you pass the swimming pool on foot, stop in your tracks to calculate and stare. Let images flash past your eyes of your frolicking self. You: dog-paddling in circles. You: taking a cannonball leap from the high diving board. You: emerging from under the water in a splash of chaos and light. Imagine yourself in the pool with friends. Imagine yourself in the pool alone. Imagine yourself in the pool with horses and dogs. Tell anyone who will listen, or tell yourself, that you have a mind to knock on the owner’s door. You will seek permission to swim in their pool for today, only just for today. Decline all opportunities to actually knock.
