The character who said "A rule is a rule" is Dr. Joseph Pallini, the assistant principal. The platitude means, when the rule was made you can't change it you have to deal with it. That basically means that Philip has to go with the flow and listen to the rule, not deny it. This rule is a part of my life, because there are rules everywhere you go. Theres rules at school you have to listen too, and rules about the law. We have to listen to those rules. If you decide not too, something just make come back and strike/shock you.
