Movedalot are you really saying you have never ever been less than fully truthful? I am not talking about the whoppers, but the little prevarications. 'How are you feeling? Fine', even though you have a very slight headache, runny nose etc, those minor ailments not worth mentioning. Never in the months after a bereavement pretended to feel better than you do because to burst into tears and weep over everybody who inquires sympathetically every time would drive everyone away, particularly when you do not know them that well?
I find the example you give in your post a puzzle, I would call that a lie. While 'This is the trust which has kept our family so close and our marriage together for 45 years.' , well many others of us would say that we also have families that are close and have absolute trust between members - and 45 years of happy marriage - without ever aspiring to your level of truthfulness.
