I have been thinking about the topic because my idiot relative, the one I asked not come back on my property, has always lied about thing since he was really little. Even things that he got caught redhanded doing - he lied and said he didn't do it. My grandma even washed his mouth out with soap for lying, and you had to be REALLY naughty for grandma to do that. So now, at 30 years old, my brother asked him what happened when I asked him to leave from my pond and he lied and said he was there all by himself and I just ran him off. My brother and I are close and he knows I'm not lying - there were at least 6 people there that day. Plus my husband was there & saw everything, too. So I can't figure out, why would my other relative lie about it when he should KNOW he is not going to be believed? Does a pathalogical liar believe their own lies or do they remember the incident the way their story goes? Or do they know they will be caught in their lie and just not care? I'm so curious about the psychology behind it. I can well understand lying if you think you won't get caught. But after you've been caught?
