A few years before, I took a sightseeing trip to Washington, D.C. Standing outside the Ronald Reagan Center, I heard a voice to say, "Can you help me?" When I turned around, I saw the elderly blind woman with her hand opening. In a natural reflex (反应), I reached into my pocket, pull out all of my loose change and placed them in her hand without even looking at her. I was annoyed at being bothered by the beggar. And the blind woman smiled and said, "I don't want your money. I just need help to find the post office." In an instant, I realized that I had done. That blind woman reminded me my blindness. So in this essay, I wanted to be grateful to the invaluable lesson she gave me.
