As a JW teenager during the early to mid 90's I happened to be in a congregation that did ALOT of things socially. There was skating every Sunday (and the girls and boys did hold hands during the couples skate) and then out to eat afterwards as a big group.
A big to-do was always made out of graduation parties and some anniversaries. The girls occasionally had slumber parties. There was actually a congregation organized talent show once. There were also a couple of "formals" - basically substitute proms. I wasn't invited to the first one - but I was to the second one.
I remember practicing swing dancing with some of the boys and being able to really "wow" people at the party.
Then came the dealbreaker - someone hosted a big costume party. It wasn't at Halloween - but it was that general time of the year. Boy did the tounges start wagging then! There were never any big get-togethers after that. It kind of got shut down.
Virgochik - I grew up in Indiana too, and it sounds like we were in a similar area. I was born in Michigan City and then we moved to South Bend when I was eleven.
Oh, and just for the record, I call soft drinks "pop". My friends in the South call it "Coke" no matter what kind of soft drink it is. Funny, huh?
