Steve and I pulled trash for four solid hours continuously, except for about five minutes when we stopped to talk. My shoulder hurt badly each time I put another full barrel on it, and my legs occasionally trembled as I was heading for the street. But the rest of me said, “Go, trashman, go.”

I could not have imagined there would be joy in this. Dump. Lift. Walk. Lift. Walk. The hours flew by. Saturday meant many people were outdoors working in their gardens or greenhouses. Most of them looked approachable enough. There wasn’t time for lengthy talks but enough to exchange greetings that go with civilized ways. But I was shocked to find that this wasn’t the case.

When I said hello to them, most often the response was either nothing at all, or a surprising stare because I had spoken.

One woman in a housecoat was startled as I came around the corner of her house. At the sound of my greeting, she gathered her housecoat tightly about her and retreated quickly to the door. I heard the lock click.

Steve complained angrily on the long ride to the dump: “They don’t realize we’re humans.”

I had originally planned to stay at this employment for only two days but now I’m going to continue. I have decided, too, to keep saying hello in people’s yards. It doesn’t do any harm, and it still feels right. Frankly, I’m doing an essential task. I left this country a little cleaner than I found it this morning. Not many people can say that tonight.

John Gardner wrote that a society which praises its philosophers and looks down on its plumbers（管子工）is in trouble. “Neither its pipes nor its theories will hold water,” he warned. He might have gone a step further and called for respect for both our economists and our trashmen; otherwise, they’ll both leave rubbish behind.
