People sit in a circle and whisper a secret saying to the person on their right.
By the time the saying goes all the way around the circle, it has often changed completely. But it is based on the principle that we are imperfect people with imperfect hearing and imperfect memories. When gossip is more than a game, it can become quite cruel. Our imperfections can deeply hurt other human beings. It is because of this that the scriptures warn us not to be a whisperer who bears a tale.
