angry men and dark alleys

I was walking home from the coffee shop this evening--it was after midnight and the joint closed shortly after I'd ordered my drink. I was chatting to my friends about trivial things when I heard the sound of a man shouting up the street. It was not street preacher shouting, but the shouts of a man who is violently angry. We had just turned in that direction, and after a few paces, we saw the man up ahead. He was approaching.

We dodged into an alley to avoid confrontation, and dodged out as soon as we could to avoid getting mugged. I can't help wondering who that man was, why he was angry. What happened to this man, this angry man, that was walking down 45th street late at night?

I almost wish we hadn't avoided him, had at least waited to listen to what he had to say. If he had anything to say.
