I ask this as a serious question. Several here have posted that they have dealt with "Casey-like" family members. Is pretending that you believe their lies the recommended way to deal with this type of personality? How exactly do family members deal with these folks? I cannot believe that the manner George and Cindy Anthony are using - making up explanations and excuses for the daughter's poor behavior - is what any mental health professional would recommend. Or is it? Any input from those who have "been there" would be appreciated. I know that I am witnessing familial dysfunction. I just would like to try to understand what I am seeing a little better, if possible.
