Sure, we all lie from time to time. But some people lie a lot more than normal. There are those who lie on a regular basis because they have low self-esteem and want to look better to everyone else by lying a lot. Although I don't think that all individuals who lie a lot are necessarily bad people, how are you ever supposed to trust someone who lies excessively if you've decided that you're aren't going to put up with the person doing so? The answer is that you shouldn't trust the individual, or at least not at first. In order to starting trust the person, he or she must be truthful on a regular basis over an extended period of time. Liars are so used to lying that they aren't going to suddenly be truthful on a consistent basis at first. However, over time, if the person tries to change, he or she can become someone you can trust.
I'll respectfully disagree. Lying is a particularly pernicious habit, and I've never known a habitual or pathological liar who 'tried to change'.
Trust isn't necessarily a blanket either. I know people who couldn't tell the truth if you paid them - but they'd never steal from me and I'd trust them with my life. One fella - well, the truth is just boring to him LOL
I see what you're saying, Shadowwalker. Take my brother, for instance. He lies a lot. But he's not a sleazy type. He would never steal from anybody or scam anyone.
