We feel trapped or confused or like we've a part to play. So we let the truth slip or artfully forget to include essential details. Information that if given might affect other people's decisions. Those whose slips and omissions are best delivered (or not) are done so to others with absolute faith or accepted blindness. Either that, or they're just delivered without a scent - undetectable like Radon. Of course, there are the more innocent who were raised without constant secrets and dishonesty. For them, they leave paper trails and evidence - a scrapbook of all of the times. A biography told by the gaps given others. And the card attached would say: We are all honest when we absolutely want to be.
