I was walking past an office building in San Francisco when I saw a pigeon trapped inside the lobby. It was frantically beating its wings, throwing itself against the glass again and again. The lobby was crowded with people, but everyone ignored the bird, stepping around it as they hurried on their way. Not a single person was willing to stop what they were doing. I went into the lobby. I took off my jacket and gently draped it over the pigeon and then I picked it up, crossed the room to the automatic sliding doors and opened my hands. Instantly, the bird fluttered up into the sky. The people continued to hurry along, oblivious to the moment, to mercy, to the beauty of sudden flight.
