Hmm.... How do they get the parents to pay? Is it an actual legal fine that you'd have to go to court for? (I figure that's the case if your child injures someone physically, right?)
But anyway, I feel like the world is actually improving in the kids-will-be-kids department. In the past, when kids did something their parents didn't want, it's because they were being "defiant," or "disrespectful," or otherwise just deliberately being a hurtful person. And that's still a popular opinion, but it's changing.
