Once, when I was walking up Sixth Avenue in Manhattan, I saw a nicely dressed older man standing in the street beside the curb. He was turning around in small, distracted circles. All my prejudices against the city came up: here was a man in need, but people were walking by, evidently uncaring. In Texas, we wouldn’t let a confused old man place himself in danger. I approached him as any gallant Texan would and said, “Sir, are you okay?” He looked at me in puzzlement. “I’m waiting for a cab,” he said.
