Even 'white lies' destroy trust and you can never get trust back. A wise woman once said 'you better have a damn good memory if your going to lie'. Liers have the worst memory. I have zero tolerance for lies.
They lie. That is their hallmark. They believe their lies. They deceive. (It was a 'white' lie.) They obfuscate. The fake emotion. They half-truth. Then, they turn around and accuse you of doing the same. You, as a normal person, can't even comprehend.
