If their lips are moving, they are lying. That is what I've come to accept. I catch my wife in so many lies. I don't even try. She says she stays late after the AA meeting to help with "board of directors". Right. Then, the next morning she asks me to get 5 bucks out of her wallet for our daughters lunch money, and a receipt for a bottle of wine from the night before falls out.
Repeat this 50 times since the summer. She lies when the truth works just fine. Did yours? I bet I know the answer.
