existential angst at a bus stop

A man at the bus stop said something to me while I walked by yesterday. I didn't hear what he had to say--it rhymed with twain. I think twain might have even been the last word, but I don't know why. What could he possibly have said? Was he talking about Mark Twain? It was after midnight and I was the only person in earshot. Was he talking to me? I thought. I turned to look at him for a moment, about to ask him to repeat himself. But I didn't. I kept walking. My thought process now baffles me--I assumed that there was nothing interesting about me, so he must not have been talking to me.

I was wearing a black hooded sweatshirt, jeans, and Converse all-stars. I had a red t-shirt rolled up under my arm, or possibly in my pocket. Do I look approachable? Do people often start conversations with lines that I can't make sense of? Why didn't I stop? He didn't look threatening. But I couldn't think of any words that rhymed with twain that meant anything to me. I kept walking.
