"I'm afraid I can't."
"Why not, Citizen Morgan?"
"Is this a trick question? Everyone knows that teachers aren't allowed in the closed classes."
"Who is allowed in?"
"The children, of course."
"But who teaches them?"
"The government is in charge of that."
"Of course. But who, specifically, does the teaching in the closed classes?"
"I have no idea, sir. It's none of my business. The closed classes are an ancient and respected institution. What goes on in them is quite possibly of a religious nature. But that's only a guess. Whatever it is, it's none of my business. Nor is it yours, young man, Opinioner or not."
"Thank you, Citizen Morgan."
