Hey, dad, as soon as you can, get one of Steve Hassan's books, as Under 74 said. http://www.rickross.com
They smile at you and speak in simple sentences and try and appear as loving and unassuming as possible. At the same time, they would be afraid to touch any food you had cooked for fear of demons. The best you can expect from JW's in a crowd is benevolent tolerance.
Your daughter is in trouble, but you can do a lot of damage bulling in with all the information you are finding on the INTERNET. JW's fear the INTERNET far more than "worldly people". Get Steve Hassan's book.
