I taught a life drawing class the other day. It was late in the term and there was a test coming up soon, so I’d been giving the students little pop quizzes to help them prepare. That day, we had a model in and I had to ask him to wait while everyone did this quiz. He laughed. “It’s like all those bad dreams rolled into one. I’ve shown up for class naked, and there’s a test I didn’t study for.”
