The kids get it but some of the adults don't. I think it's because children are always being shown something different and the world is so new to them. They can accept learning new things constantly.
The biggest danger I have seen is letting the adults and parents accept bad behavior because it was "an accident" or it was a "mistake". I told our kids if they shoot me, I'll just shoot them back. One kid who always got away with anything he wanted to because the parents went through a bad divorce finally understood I didn't believe in accidents.
It also helped they didn't know I was bluffing.
I take a lot of heat because I truly do not believe there is any such thing as an accident when humans are involved. Of course the flamers have yet to give me an instance that I could not pick apart.
