While visiting my mother in the hospital, I stopped in the cafeteria for breakfast. I set a piece of bread on the moving toaster rack and waited for it to pass under the heated coils and return golden brown.

Instead, it got stuck at the back of the toaster, and I couldn't reach it. The woman next to me in line quickly seized a pair of tongs, reached in, and fished out the piece of toast.

I joked, "You must be an emergency room worker."

"No," she replied with a grin. "I'm an obstetrician."
