This "our kids are better than your kids" point is one of the first things that made me wonder about JWs. Double life thing, again. I am not JW and the JW Mom I was speaking to was telling me about the wonderful kids in her congregation and what a good influence on each other they were. Meanwhile, I knew her 14 year old son went out partying and drinking with older JW kids and had all sorts of stories about what these kids were up to. I don't think JW kids are WORSE than other kids, but this parent was in full scale denial.
This particular boy has cleaned up his act, yet still, hangs out with the wilder kids at school, and self-righteously judges their behavior, and once again talks about how JW kids are better, and yes, some JWs are better than how some of those kids act. Just like some worldly kids are better than some JW kids. Those generalizations are just too big.
There are parents that choose not to be involved with their kids, or who close their eyes to their kids less desirable behavior. The thing I have noticed with my kids' friends, is the ones who seem to have their head on straight also seem to have involved parents who are willing to drive them around, have other kids over, have standards of behavior, care about marks and doing your best. These kids come from all religions, Jewish to Pentacostal to Buddist, and different backgrounds, but the common factor is that they all have parents who care, who listen and who are willing to be parents, not buddies.
