Take your cue from Einstein

ALBERT EINSTEIN had a disregard for the tyranny of custom. Once as guest of honor at a dinner party, he was called on for a speech.

“Ladies and gentlemen, I am sorry, but I have nothing to say,” he said and sat down. Arose and added, “In case I do have something to say, I’ll come back.”

6 months later he wired the president, “Now I have something to say.” Another dinner was held, he made his speech.
