The Apple Doesn’t Fall Far from the Tree
Kids learn a lot from their environment, and they also learn a lot from their parents. A lot of kids imitate the kind of behavior they see at home, so if you see a kid misbehaving in school or a public place, it’s safe to assume they learned this kind of behavior at home, or at the very least, that their parents might not condone this kind of behavior.

Kids always mess around and most of the time their actions are harmless – they just want to have fun and they don’t necessarily know any better. So, we don’t fully blame the kids who filled up these containers with ketchup – we blame their parents for allowing them to do so, shouting at customers who tried to complain.
