Always use stories where possible to illustrate points.  People can hear rules and laws but find it difficult to remember the details.  Humans are much better at remembering stories, because we are wired to learn from others when they tell their experiences.  Stories are also more likely to elicit emotions, which make them easier to remember and to learn.  As often as possible, use stories to illustrate your rules or policies.  It will help your audience to remember the things they are supposed to learn.
