I snapped awake at the sound of subdued screaming music spilling from the headphones of the teen who had just settled down on the seat next to me. I glanced over at her, and she flicked her gaze in my direction, as if daring me to say something. But I was preoccupied by the feeling that something was wrong. I shook off the disorientation and saw that I was several stops away from where I needed to be. As the subway train rolled to a stop, I leapt out of my seat and navigated my way to the doors. I was late to work, and on a day after I may have burned one bridge too many.
