On a recent trip into the city, I noticed people stationed on several street corners. Their clean, coordinated T-shirts announced a common goal—to help end homelessness. One of them approached me offering information. As I paused there on the street, I noticed a homeless man standing just a few feet away. I saw his scruffy outfit and downcast look. Although the advocates for the homeless were doing a good thing, they seemed oblivious to the man. No one spoke to him or offered him food.
