There was a guy on the platform this morning, zigzagging close to the edge, babbling. I was lost in thought until I realized he was coming my way. I backed away and hid behind a beam, a little worried that he’d be offended and lash out. We got into the same car and he sprawled out on the bench across from me, chanting and moaning to no one and nothing. He had a belt in his hand and began whapping the buckle against the back of the seats. It made a hell of a racket. He seemed pleased by it, like a baby banging on the bars of his crib. Others in the car peered over their books and tablets at him for a moment, then didn’t give it another thought. “It’s too damn early for this,” said a woman across from me to the right. We caught each other’s eyes and smiled just a little bit.
