I was tuning a piano at a day care center. A young male child said “What’s that old man doing?” To quote Hamlet when he spoke to Polonius, “Yourself, sir, shall grow old as I am, If as a crab you could walk backwards.” But in this case it would be walk forward. You see Hamlet was younger than Polonius and to become as old as Hamlet, Polonius would have had to grow younger, or walk backward, so to speak, like a crab. So in this case with me and the dear young commentator, crawl forward as a turtle would have been a more appropriate expression than walk backward as a crab. But in any case , someone shushed him and I tuned the piano.
