Teaching is a tremendous responsibility, said Blurtso. Yes it is, said Harlan. What if I’m no good at it? said Blurtso. You’ll be fine, said Harlan. What if my students ask questions I can’t answer? Then tell them you don’t know, said Harlan. Can I do that? said Blurtso. Of course, said Harlan. I thought a teacher was supposed to know all the answers, said Blurtso. No, said Harlan, a teacher is supposed to know the questions. The questions? said Blurtso. Yes, said Harlan, the questions are more important than the answers. They are? said Blurtso. Certainly, said Harlan. Why? said Blurtso. Because many questions, said Harlan, have many answers, and others have no answer at all. So all I have to do is ask questions? said Blurtso. Yes, said Harlan. What kind of questions? Good questions, said Harlan, questions that make your students consider things they’ve never considered. How do I do that? said Blurtso. It’s easy, said Harlan, just do what you’re doing right now. What I’m doing right now? said Blurtso. Yes, said Harlan, asking questions.
