I was strolling down Main Street this evening, when I passed a beggar sitting on the sidewalk and shaking his begging bowl in front him. As I neared him, a couple was approaching him from the other direction. The beggar shook his bowl in front of them to ask for alms.
The man looked surprised and said, "But I just gave you some money a little while ago while we were going in the other direction!"
The beggar replied cheerily, "Oh, I'm sorry. I seem to have forgotten. Indeed, you are right."
I passed on. After a few steps, I turned to look back at the beggar again. He was blind.
