English Original
Rodents had overrun a posh private school near New York City. The headmaster, a friend of mine, asked a health inspector to deliver a slide presentation to teachers and students, showing how to remedy the situation, such as properly storing trash and prohibiting food in classrooms.
The following day, a teacher had her very young students write a thank-you letter to the inspector. One student wrote:
"Dear Mr. Johnson,
Thank you for coming to my school. Until I saw you, I didn't know what a rat looked like."

啮齿动物在纽约市附近一所高档私立学校里泛滥成灾。校长（我的一位朋友）请来一位卫生检查员，为师生们做了一次幻灯片演示，说明如何改善这种情况，例如妥善存放垃圾、禁止在教室内吃东西等。
第二天，一位老师让她年幼的学生们给检查员写一封感谢信。其中一个学生写道：
“亲爱的约翰逊先生：
感谢您来到我的学校。在看到您之前，我还不知道老鼠长什么样。”
