You guys forget how different your minds were when you were adolescent, or children. Children are far more open to suggestive thinking than we are, in the five years I've had my kids I've only ever had to spank them twice. Now they understand when I give them "that look" they instantly recall the last time-- that suggestive thinking works it's way into your mature mind, so eventually you'll deviate- Do the wrong thing on occasion, but your mind still has that subconscious recall, your mind has been structured this way; if it lacks that structure chances are you'll continue to deviate until disaster.
