Europe is a lot more relaxed and kids are given a lot more freedom. When we were kids we just were expected to wait for the other sibling and take a 20min tram ride home together. At 15 I probably started spending nights not at home occasionally (I also never caused any real trouble, so we built trust with my parents).

Though there was a difference if you as a Central European visited France for example. The kids were way behind us in being relaxed and confident without parents around.
