No rules, but there are reasons

From "Young Indiana Jones and the Mystery of the Blues" when Indi was being taught about Jazz. He was trying to learn the rules of Jazz when informed by his mentor, "there are no rules, but there are reasons". In life, when dealing with people, often there are no rules. People are illogical and emotional frequently. They are not following rules, but they have reasons. We must respond with flexibility and the ability to flow with others.
