Our crew at an ambulance company works 24-hour shifts. The sleeping quarters consist of a large room with several single beds, so we get to know one another’s habits, like who snores or talks in his sleep. While I was having my teeth examined by a dentist one day, he noticed that some of my teeth were chipped.
“It looks like you clench your jaw at night,” he said.
“No way,” I blurted without thinking. “No one has ever said I grind my teeth, and I sleep with a lot of people!”
