I am not sad, he would repeat to himself over and over, I am not sad. As if he might one day convince himself. Or fool himself. Or convince others—the only thing worse than being sad is for others to know that you are sad. I am not sad. I am not sad. Because his life had unlimited potential for happiness, insofar as it was an empty white room. He would fall asleep with his heart at the foot of his bed, like some domesticated animal that was no part of him at all. And each morning he would wake with it again in the cupboard of his rib cage, having become a little heavier, a little weaker, but still pumping. And by the midafternoon he was again overcome with the desire to be somewhere else, someone else, someone else somewhere else. I am not sad.
