The TRUTH itself is rigid, immutable, inflexible. You either did it/said it or you didn't. Now it is the different VERSIONS of the truth that get you into trouble. Also an ever-changing view that flips unpredictably is something no one can predict include the flipper. You cannot know what the person you represent thinks/wants at that very moment since he/she may have had a change of heart/mind. So who in his right mind would go out and talk on behalf of another whenever? Would you want anyone speaking for you ever?
