Disfunctional subway

Strange night on the trip home tonight. Coming into the 23rd St subway, a muttering man was crawling under the turnstile, in full sight of the station attendant. I went through after him, watching him wander up and down the platform, his voice rising and falling against the subway walls. I went back out the turnstile, and went to ask the attendant if she would call someone to help him, maybe see if he needed medical attention. I have this irrational paranoid tingle about people throwing themselves off the platform too. The attendant, sitting under the "if you see something, say something sign" refused to help, saying there was nothing she could do. Of course there was, she just chose not to. As I went back to the turnstill, there was a girl there, maybe 19, 20, standing at the entrance, softly asking for help as people passed. Part of me wanted to stop and ask her what she needed. Part of me, that empathetic-less part, pushed me back through the turnstile. A few minutes later I saw her on the platform, angry, spitting at the train as it passed, reaching her fingers out to the rushing cars. And the cold part of me turned away.
