Many adults today have forgotten these "rules of the game."
Storytelling traditionally begins with a "Once upon a time..." opening. and then a storyteller’s silent pause to gather his thoughts. The traditional openings, of which there are many (often with responses from the audience), were "rituals" that served as a signal that the teller was suspending "time and space" as we know it and transporting the audience to a world of imagination and play. They identified the teller and established the audience’s commitment to accept for the moment that imaginary world and its "rules". Similar "rituals" also signal the end of the story and their return to reality. Many adults today have forgotten these "rules of the game." There are online lists of Beginnings and Endings.
