It's true for many of the JW children, they miss out on a lot growing up in such a strict household. Holidays and being with their extended, non Witness family is very unfortunate. But many of the young people seemed to do a good job leading a double life at the hall I attended before walking away. So I'm not sure they missed out on much when it comes to sex and drugs. I was only an elder for a little over a year but I became very critical of the teenagers at the hall. It seemed that most were doing "bad things" that makes their deity sad.
Made for many a late night after meetings.π
