Good luck-my sister and I were raised by the same mother (other than the occasional white lie-not a huge fibber)-I was honest almost to a fault and my sister would lie through her teeth about anything growing up. I was almost jealous of her skill with this-LOL. My mom could tell just by looking at me if I was lying to her, but not my sister. I can't say that anything my mom ever did with her really worked-and she ran the gammut from lectures and grounding to a full fledged beating (that was only once), but the one thing she did do that was somewhat effective was to treat everything my sister said as a lie. It wasn't foolproof by any means, but it really bothered my sister that when she was actually telling the truth my mom wouldn't believe her, but she couldn't argue against my mother's logic of, "Well how can I trust you if you lied about such and such?" She would stress to my sister that she would have to rebuild the trust from square one and anytime she got caught in a lie, she would start all over again with ZERO (and I mean zero-my mom did NOT play) privileges and earn them back one by one.
I'd like to tell you that as adults she outgrew it. I give her the benefit of the doubt a lot of times, but I think she still lies about a lot of stuff. Again-good luck.
