During my second month of nursing school, our professor gave us a pop quiz.
I was a careful student and had breezed through the questions until I read the last one: "What is the first name of the woman who cleans the school?"
Surely this was some kind of joke. I had seen the cleaning woman several times. She was tall, dark-haired and in her 50s, but how could I know her name? I handed in my paper, leaving the last question blank.
Before class ended, one student asked if the last question would count toward our quiz grade. "Absolutely," said the professor. "In your careers you will meet many people. All are significant. They deserve your attention and care, even if all you do is smile and say 'hello'."
I've never forgotten that lesson. I later learned her name was Dorothy.
