Human history begins with stories. Some stories are so important that they(pass) down for countless generations. And storytelling is a useful tool, gives a lesson much more powerfully than other ways. For example, once I had to tell actors to be on time for a performance. Instead of(repeat) the time over and over again, I told them a true story. "The year before, one of the actors was late. We replaced him so he didn't get a chance to perform." Then, no one(be) late again.
