My paternal grandfather’s favorite holiday was April 1. He would spend months putting together some trick to fool either a family member or a friend. Both were assessable to his “tricks.”
He could read a person and within a few moments have an idea of what the best trick to play on that person. Nobody really saw it coming. They knew his reputation, of course, but he was so skillful in his acts of foolery that nobody ever guessed they were a target until was too late.
One thing I learned from my grandfather is that it is almost impossible to fool the Fool-Master. If he had spent as much time being a grandfather as being a reputable Fool-Master, he would have been the greatest grandfather in the world. His priorities, however, were not in that direction.
