The sun is shining when I get on No. 151 bus. We passengers sit jammed together in heavy clothes. No one speaks. That’s one of the unwritten rules of Chicago commuting. Although we see the same faces every day, we prefer to hide behind our newspapers. The phenomenon is striking: people who sit so close together are using those thin sheets of newsprint to keep their distance.
As the bus approaches the Magnificent Mile, a voice suddenly rings out: “Attention! Attention!” Papers rattle (发出细小声). Necks crane (伸长). “This is your driver speaking.”
We look at the back of the driver’s head. His voice has authority.
“All of you put your papers down.”
The papers come down, an inch at a time. The driver waits. The papers are folded and placed on our laps.
“Now, turn and face the person next to you. Go ahead.”
Amazingly, we all do it. Still, no one smiles.
I face an older woman, her head wrapped tightly in a red scarf. I see her nearly every day. Our eyes meet. We wait, unblinking, for the next order from the driver.
“Now, repeat after me…” It is a command, delivered in the tones of a drill sergeant (操练军士). “Good morning, neighbor!”
Our voices are weak and timid. For many of us, these are the first words we have spoken today. But we say them at the same time, like schoolchildren, to the strangers beside us.
We smile and can’t help it. We have said it; the barrier has been broken. Good morning, neighbor. It is not so hard after all. Some of us repeat it. Others shake hands. Many laugh.
The bus driver says nothing more. He doesn’t need to. Not a single newspaper goes back up. I hear laughter, a warm sound I have never heard before on bus No. 151. This day is starting off better than most.
