Hi Wolfeyes1 - That's a good question. Maybe for some - they do this because there's something they want, and you can provide it for them - if they figure they can say/do various (manipulative?) things. Or - depending on what the situation is about - maybe they want to hide something about themselves. Maybe I'm trying to simplify others' lies (to think about this in terms of rewards - for themselves). Do you have any ideas?
