I like your short and sweet answer TotallyADD. But, no one who calls will hear what you say.
It would probably be better to say that you, as head of the household have decided, that you and your wife will be researching your beliefs and will get back to them when you are finished. If you want to get Df'ed you could add ", because of the hypocrisy of the GB". At least by you taking the fall, your son may still want to have a relationship with your wife.
Peace be with you and everyone, who you love,
Robert
