Fan Casting Troubling Unchildlike Behaviour in Sort by Tropes

Kids should be kids, at least that's how the saying goes. That means worrying about kid things and doing kid things, such as playing outside, watching TV, going fishing, or whatever it is that kids do locally. What we don't expect kids to do is to drink alcohol, smoke, have sex, use drugs, hitchhike, commit violent crimes, or do other things we only associate with adults and older teenagers. Yes, many adults get upset when a 15-year-old drinks beer, but when a 10-year-old does it, outrage turns to concern and worry.
