just tell him (i have) that our stink-o-meter is much much better than his ability to lie. It's not an insult to him, it just means he's not as evil and conniving as our abusers, or just the people we grew up with in general, were! so he should get over himself. we understand it might not be in our best interest for him to always say the first thing that comes into his head, but he shouldn't put it on us, either, when we catch him overdoing it. this is some bad game-playing on his part and we don't deserve it. how is it therapeutic to try to make us doubt ourselves to preserve his stupid ego???
