My Man Jeeves

"Directly Stella Vanderley broke off our engagement I -"
"Broke off your engagement? How long were you engaged?"
"About two minutes. It may have been less. I hadn't a stop-watch."

"How do you mean, forgotten?" I said. "Forgot-ten whether it's the twentieth or the twenty-first, or what? How near do you get to it?"
"I know it came somewhere between the first of January and the thirty-first of December. That's how near I get to it."
