I had a couple of attractive JW girls in my graduating class. They were very normal, maybe a little wilder than average but not too much. One of them had a crush on me in something like 4th grade. I was too much into Star Wars and sports at the time. In retrospect, the Vikings and Cyclones have been pretty frustrating over the last approximately 4 decades.
Oh, see, complete opposite for the ones I knew. But, I think that was probably because almost 90% of people who profess a faith (not counting "no religion) in Dubuque County were Catholic, so anyone not Catholic tended to either avoid talking about their faith, or if they were up front about it, they tended to be close knit with their faith only. It really was a weird dynamic growing up in such an environment, especially when you add in the lack of racial diversity.
