I know, each family have it particular caracteristics, but, there's always something that belongs for all of them in a determinated culture.
What i see from Brazil in us movies is that the parents really don't care much about their teenagers, letting they go out whitout telling where they are going, let them sleep over whitout asking permission or at least calling home, don't talk with their children about everyday stuff. And things like that. Sure, movies aren't the best way of knowing about a place.
