The J train is usually fairly empty toward my stop. It's that close to the end of the line. It's also the middle of the night. There are four other passengers in the subway car. They're all sideways.Nope, I'm sideways.I must have knocked out hard. I'm lying on my arms and ribs. My legs stick out over the edge of the bench, bending the wrong way at my knees. I remember one time I'd nodded off and fallen out of a subway seat.
