This is a story of a man who works in my factory. I have seen him for years, but I didn't know him very well. He was a little bit weird (怪异的) . He always wore an old red hat and carried a rubbish bag. He seemed to have no friend, and was always alone. He usually spent his break time and his lunchtime walking around in the factory and collecting used tins (金属罐). Maybe he was too poor, I guess. But I didn't care much about him.
One day, I was fixing one of the broken machines in the factory when this "tin man" came with his bag. As usual, he picked up the tins, which were all around the place. My manager was standing there, watching me.
When I finished my job, I heard my manager ask the "tin man" about what he was going to do with those tins he had collected. I never even thought about this kind of question, because I always assumed that "tin man" would take those tins to the recycling center.
Unexpectedly, the "tin man" answered, "I will give these tins to my neighbor. He has been ill for many years and cannot work. He is too poor to buy daily bread now. "
I was so shocked to hear that, so I asked him, "You mean you collect all those tins just to help your neighbor?"
"I know this does not help much," he said. "But I give everything to him, because he cannot work. He needs help. "
It was the most beautiful moment in my life. We are all able to help others no matter we are rich or poor. It has made me feel humble (谦卑的) every day since then.
