I was driving around downtown one afternoon in the winter. I   1  a red light and stopped. As I was   2 , I saw a young guy standing on my left. He was   3  in the face and holding a cardboard sign with some   4  on it. When you’re in the heart of downtown, it’s pretty   5  to see homeless people asking for   6 . Generally, I would pass them, but this time when I glanced over the sign, I   7 
I can’t remember what the sign said exactly, but it was something like: “  8  money / food, have stomach cancer, homeless, anything helps.”
I didn’t know why, but for some   9  this particular sign struck me. The   10  had just turned green, and there was a line of lunch rush hour traffic behind me. I went back and forth in my    11  a hundred times in that next   12  about whether I should do something. “Should I help?  13  on? Should I do something?”

The traffic moved  14 , and I went with it. About a block(街区)or two away, my heart had sunk simply for this guy. I felt so   15  for him. So, I decided to go back and ask him  16  I could buy him lunch and hear his story.
It took me about five minutes to   17  and back on to the same street where I had seen him. It was just five minutes — but he was   18 .
“Where did he go so fast?” I wondered. So, there was   19  left to do except drive on. 
If you get a special nudge(想做的事)from inside you,   20  consider acting on it. Don’t miss out — for yourself and for that other person.
