She was a successful ad sales rep in Manhattan. He was a homeless, eleven-year-old panhandler on the street. He asked for spare change; she kept walking. But then something stopped her in her tracks, and she went back. And she continued to go back, again and again. They met up nearly every week for years and built an unexpected, life-changing friendship that has today spanned almost three decades. Whatever made me notice him on that street corner so many years ago is clearly something that cannot be extinguished, no matter how relentless the forces aligned against it. Some may call it spirit. Some may call it heart. It drew me to him, as if we were bound by some invisible, unbreakable thread. And whatever it is, it binds us still.
