I don't usually cry when I see those people on the streets. This past Sunday my mother and I spotted a woman hardily pushing three loaded shopping carts across the street, under the blazing sun in a ragged tanktop.
I still didn't cry.
I think maybe just the idea of one human, suffering, calling out to someone, somewhere out there just brings the emotions we suppress in our daily lives out to the surface... :] I'm glad you got the DD too. It's hard to find shots like these.
