Buster is a homeless man who says he's been living on the streets of Washington, DC for at least the past 10 years. He is also profoundly depressed, speaking only in a whisper and rarely making eye contact. While he is panhandling in a very busy spot during the morning rush hour he is totally ignored because he does not have the energy to engage passersby. As with other homeless men and women in my city Buster is one of the Invisible Ones who is at the mercy of both the weather and the indifference of those who choose not to see him. If you see Buster near the George Washington Hospital Center, or someone like him, stop for a moment and have a conversation. Ask if you can help out in some way. I guarantee you'll both feel better for having had that experience.
