I've always had difficulty dealing with people who are less than truthful. My personality wants to correct the lack of honesty and make everything right. The problem with that is the dishonest usually have convinced themselves that what they are saying is true. No barrage of facts can convince an individual if they don't first concede their will. Herein lies the problem. So being a guy who believes that all of life's answers lie in the owner's manual, (the Bible), that's where I go for the answers. Low and behold if they didn't address this issue too!
"As for a man, (or woman), who is factious after admonishing him, (or her), once or twice have nothing to do with him, (or her), knowing that such a person is perverted and sinful; he, (or she) is self condemned."-Titus 3:10-11 (__) added for gender fairness.
Ah, the time I could have saved if only I'd first turned to the operator's manual!
