Three Umbrellas, One Stand

Noa works at a small café downtown. An umbrella stand sits by the front door. It always holds exactly three umbrellas.

诺亚在市中心的一家小咖啡馆工作。前门旁边放着一个雨伞架。里面总是正好有三把伞。

On rainy days, many customers borrow one. They walk out with a dry umbrella. Noa expects the stand to look empty by night.

下雨天，很多顾客会借一把伞。他们撑着干爽的伞走出去。诺亚以为到了晚上，伞架会空空的。

But it never does. By closing time, three umbrellas always stand there.

可是从来没有。到打烊的时候，总是有三把伞立在那里。

Noa asks her coworker Brice about it. "Do we hide extra umbrellas somewhere?" she asks.

诺亚问同事布莱斯这件事。“我们是不是在哪里藏了多余的伞？”她问。

Brice shakes his head. "Not that I know." "Maybe it is just good luck," he says.

布莱斯摇摇头。“就我所知没有。”“也许只是运气好吧，”他说。

Noa does not believe in luck like that. She decides to watch the stand all day.

诺亚不相信这样的运气。她决定整天盯着伞架。

A man borrows an umbrella at noon. An hour later, a woman returns a different one. A teenager takes one, then brings back two.

中午，一个男人借走了一把伞。一个小时后，一位女士还回了另一把。一个少年拿走一把，后来却还回了两把。

Noa watches this pattern all afternoon. People borrow, and people return, again and again. The stand always settles back to three.

诺亚整个下午都在观察这个规律。人们借，人们还，一次又一次。伞架总是回到三把。

"I understand it now," Noa tells Brice. "Our regulars share umbrellas like a small library. They just keep the system fair."

“我现在明白了，”诺亚对布莱斯说。“我们的常客像一个小小的图书馆一样共享雨伞。他们只是让这个办法保持公平。”

Brice laughs. "There is no mystery at all."

布莱斯笑了。“这根本不是什么谜。”

"There is a nice one," Noa says with a smile. "Our customers take care of each other."

“这是一个美好的谜，”诺亚笑着说。“我们的顾客互相照顾。”

That evening, Noa counts the umbrellas once more. Three umbrellas stand by the door, as always.

那天晚上，诺亚又数了一遍雨伞。门边立着三把伞，和往常一样。
