I've noticed that when a Witness kid goes out of the organizaiton, they do it in a big way. First off, there's just the wanting to let your parents know that they are going to do things the parents hate (which is typical of most teens, but JW kids have so many rules thrust upon them, there is just so much more to rebel against.) I've seen them get into drugs, dangerous sexual practices and join the military. It is a rubber band effect. The parents pull so hard to keep them in the "Truth" that, when they lose their grip, the kid goes flying the other way.
