This afternoon, after I crossed back into University Heights, carrying bananas in one hand, someone called from behind me. I turned to see a bearded fellow who had seen my strapped, slung-back Leica Q2. He asked if I would take his photograph—because he was interested in modeling. Ah, okay.

I responded cautiously, but welcomingly, because that’s the kind of delaying ruse a thief might use. But he seemed to be genuine enough, there was good distance between us, and I was situationally aware of his movements and my exit options along an extremely familiar route.
