I know - Jehovah's "happy people" are wrecks. I'd like to know how many people from my generation are still in, but none of us are in touch. (Well, actually, that's not true, one turned in to a rabid elder who emailed from time to time. We ignored him and he stopped.)
Looking at a congregation today and tell them that most of their kids will not stay in?
Where I am right now they do know - but no one's discussing it. Head in the sand to the end!
