In America you have to sue. It's a customary thing to do.
Other nations may think a little bit differently and take risks of life into account.
The best thing for stupidity is to sue. But remember to grow your children in an American way: let them do whatever they want without severly reprimanding them. After all, you might go to jail after slaping butt of your child that does not want to listen and do the thing maliciously just to make you angry.
So don't put a preassure on your kid to think. What is gonna happen? Well maybe some day your kid will get sued if he/she "accidentally" hits a person. Not very likely, right?
Important thing is to rise your kids without "stress". So let them do whatever they want (no drugs or smoking though! ... they can enroll when they are 18 so army will teach them to kill, but absolutely no liquor or smoking by 21!)
Just one thing: don't woder why there is so many freaks on the streets in the US of A who might be unppredictable and perhaps might rape someone for fun.
Just my euro-observation after 8.5 years spent here.
Hope to see you on slopes,
