Con men look for human frailty to exploit. This is most often greed. Trump found a different vice: anger. The emotional are always the most susceptible to manipulation.

Breaks in trust are infuriating and hurtful, but they don't entitle you to flame out, throw a fit, or stomp around rolling your eyes. Try to keep the steam from coming out of your ears.

As someone who specializes in deception, I'll tell you this much: When someone insistently implores, 'Believe me,' don't. Pleading 'believe me' or 'trust me' - insisting to people that you are telling the truth - is a tell-tale sign that you probably aren't.

Lying is a cooperative act. Think about it. A lie has no power whatsoever by its mere utterance. Its power emerges when someone else agrees to believe the lie.

Trump is a master obfuscator. Like an octopus escaping a predator, he releases a cloud of ink when called to the carpet on one of his many lies. His strategy? Obfuscate, then reference others. 'Millions agree,' 'everyone knows,' 'many have done it.'

Honest people remember stories in the order of emotional prominence, but liars will recount a story in chronological order. Memory rarely works that way.
