I've Never Forgotten

During my second month of nursing school, our 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 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 would 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
also learned her name was Dorothy.
