Perfect Timing
Otto von Bismark, the first Chancellor of the German Empire from 1871-90 had been conversing for a rather long time with the British Ambassador to Germany when the latter posed the question: “How do you handle insistent visitors who take up so much of your valuable time?”
Bismark answered, “Oh, I have an infallible method. My servant appears and informs me that my wife has something urgent to tell me.”
At that moment there was a knock at the door, and a servant entered with a message from his wife.
