     I work in a major U.S. factory. We make refrigerators. Four thousand five hundred new refrigerators

every day. It is a union workshop and it's gradually shrinking as many blue collar factories seem to be but

that is not what this story is about. This story is about one man who works in this huge factory.

     I've seen him around for years but never paid much attention. He always seemed just a little strange.

A little short. A little... scruffy (肮脏的). Always the same old red ball cap. And always a garbage bag

in one hand. He walks around this big old factory on his breaks and his lunch time collecting aluminum

(铝) cans. Day after day, month after month on hot days and cold days. Over the years I've followed

him as he walked to his old pickup truck on the coldest day with snow blowing and everyone with their

collars turned up and their hands in their pockets. He would be there with a 40 gallon garbage bag full of

aluminum cans. He'd toss it into the back of his truck and jump in and I'd reach my car and jump in and

we'd all race to the exit of this big half empty parking lot.

     Today I was working on a broken machine in this factory and the can man came by with his bag

picking up cans. Our manager was standing there because the machine I was working on had been

"down" for a couple of hours and he was getting worried that we might run out of the parts for one of

the assembly lines(装配线). I was finishing and I stood up just as the manager asked the can man what

he did with all those cans. I'd never thought to ask him that question because I always just assumed he

cashed them at the recycle center. The can man said: "I give them to my neighbor. He's disabled and

can't hold a job." I blurted out: "You mean you've been collecting all those cans for all these years to

give to your neighbor?" "It isn't much," he said, "but I give them to him. He can't hold a job." Right then

and there in that factory I found myself staring at him. He was wearing a T-shirt and an old red ball cap

and he had a garbage bag full of aluminum cans in his hand! I don't even know his name, but I thank him

for the lesson he's taught me.
