Some teachers, Marilyn. Mostly the really insecure. I used to turn it into a teaching lesson.

My friend's grandson, recently, corrected the teacher who was mapping out the research they had to do on a country. Now take Africa, the teacher said. His hand shot up. Africa's not a country. There was a thunderclap of silence around the room. Now the teacher could so easily have wriggled out of that, but he didn't.
