That women have periods no matter what country they're from.
無論哪個國家的女人都有月經。
Yes.
是的。
Someone actually didn't know this. And no, it wasn't a 5-year-old boy. It came from a supposedly well-educated female classmate, that was 16 years old at that time.
有人就不懂，當然這個人不是5歲的小男孩。這個問題來自一個應該受過良好教育的女同學，當時她16歲。
She was hosting a German exchange student and couldn't understand why she'd laughed so much at her question: “Do girls have periods in Germany too?”
她家裏有一個德國交換生，而且她不明白爲什麼對方聽到她的問題“德國女孩也有月經嗎？”會笑得前仰後合。
I had to explain to her why the girl had thought she was kidding and that geography wasn't a period determining factor.
我就跟她解釋爲什麼對方以爲她在開玩笑，而且地域也不是決定月經時間的因素。

I couldn’t make this up.
這個事真不是我能編出來的。
A worker in my office made a copy of a document before faxing the document.
我辦公室裏的一個職員發傳真之前先把文件複製一份。
She was assuming that the original physical document itself was sent over the phone lines and she would therefore need to copy the original before sending it because the original would disappear from our fax, and reappear at the receiving fax.
她以爲源文件能從電話線發出去，會從我們的傳真機裏消失，然後出現在接受文件的傳真機裏，所以她發傳真之前需要複製一份。
But didn’t she notice the original when it reappeared in the output tray? No, she didn’t. She stacked the originals in the feeder tray, punched in the number and walked away.
但難道源文件再次出現在接紙盤上時她沒看見嗎？她沒看見。她把源文件放在送稿托架上撥完號就走了。
Over the course of a week, or so, other workers noticed that the output tray was filling up with previously sent faxes. As a courtesy, they scooped them up and filed them away, assuming it was just an oversight or the sender was called away. Until someone noticed that the file folder had a copy of the original already in it.
一週左右的時間裏其他職員注意到接紙盤上堆滿了發完傳真的文件。大家出於禮貌把文件收起來堆在一邊，以爲只是有人一時疏忽或者發傳真時被叫走了。直到有人發現文件夾裏還有一份源文件的複印件。
That’s when the matter was brought to my attention. With a little eaves-dropping, we finally figured out who our very cautious sender was. That’s when I sent “the memo.”
我這時才注意到這件事。簡單竊聽之後我們最終知道了這個非常謹慎的發傳真的人是誰，然後我發了一個“備忘錄”。
Dear Everyone:
親愛的各位：
A quick housekeeping item for you. When sending a fax, please remember to retrieve the original document from the output bin so you may return it to the file. It is no longer necessary to make a file copy of the original. Thank you for your attention.
快速管家消息：發傳真時請記得從出紙槽拿走源文件以便放回文件夾，沒必要複製源文件。謝謝配合。
That did the trick. A few days later, the guilty worker appeared in my office to identify herself, express regret at her “stupidity,” and thank me for not having called her out specifically.
這招奏效了。幾天以後，那個內疚的職員來我辦公室承認是她所爲，而且對自己的“愚蠢行爲”表示很後悔，還感謝我沒有特別點她的名字。
All’s well that end well.
皆大歡喜。
