"Sit down, Smith," said the housemaster. "I can manage without your help."

Psmith sat down again, carefully tucking up the knees of his trousers, and watched him with silent interest through his eyeglass.

"Put that thing away, Smith," he said.

"That thing, sir?"

"Yes, that ridiculous glass. Put it away."

"Why, sir?"

"Why! Because I tell you to do so."

"I guessed that that was the reason, sir," sighed Psmith, replacing the eyeglass in his waistcoat pocket. He rested his elbows on his knees, and his chin on his hands, and resumed his contemplative inspection of the shoe expert, who, after fidgeting for a few moments, lodged another complaint.
