My heart is pounding. I want to run from the platform. As I start to leave, I sense movement to my left where the chained trash receptacles hug the sculptural outer railing next to the steps. I feel something watching me. Thoroughly unnerved at this point, I still feel compelled to know what it is. I move closer. It is a man. A dark-skinned man wearing a whitish mesh skullcap. He has on a worn dark green fatigue jacket or coat. He is crouching down and  I can’t tell if he is short or tall. Or what age. Was he there all along? He could have been because I was so intent on the looking at the water and the approach of the train. I try to edge past him toward the stair and immediately realize I have not moved at all.
