During my second month of college, or professor gave us a pop quiz. I was a conscientious student and had breezed through the questions until I read the Last one: "What is the first name of the women who cleans the school?"
Surely this was some kind of a joke. I had seen the cleaning women several times. She was tall, dark-haired and in her 50's, but how would I know her name?
I handed in the paper, leaving the last question blank. Just before class ended, one student asked if the last question would count our quiz grade.
I've never forgotten that lesson. I also learned her name was Dorothy.
