In this photo from Seoul, that I can't seem to shake, it's hard to explain this grown man begging for money, on an overpass bridge, in the rain, his jacket pulled over his head, his arms stretched before him, a few wons in his grasp. He was humiliated and humbled, certainly, now soaking wet. I wanted to know his story, and how to help him. I put a 5,000-won note in his hands – about $5. But I don't drop the money and run. I stay, yet he never raises his eyes to count his offering.
