Rodents had overrun a posh private school near New York City . So 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, i.e., stow trash, no food in class, etc.
The following day, a teacher had her very young children write a letter to the inspector, thanking him for the visit. One of the students wrote, "Dear Mr. Johnson, Thank you for coming to my school. Until I saw you, I didn't know what a rat looked like."
其中一個學生這樣寫，“親愛的 Johnson先生，感謝您來到我的學校，在跟你見面之前，我還不知道老鼠長的什麼樣子呢 ”。
