When I was in my 20s I spent some time in Europe with witness friends (who lived there...) on several occasions we all crashed in an apt guys and girls, very innocent...just a place to sleep. I remember being nervous like this was going to cause huge problems with elders meetings etc...but they brushed it off as no big deal, they did it all the time. A few of them were kids of Elders.
I noticed there weren't as many hang-ups with JWs in Europe, at least where I was.
