They don't have to push the young ones into a "rumpspringa". There is a lot of freedom among the witness teenagers these days. The kids are doing whatever they want. There are always parties, they travel (under the guise of going where the need is great), they go to their proms, they are getting paired up and dating very young and unchaperoned and no one says a thing.
When I was was growing up, there were so many rules, we literally choked and many in my age group left once they had the chance.
