Now I'm about the most safety conscious person you could meet and I
think my kids have ended the cycle of stupidity - they're not nearly as
stupid as we were. But, my wife wonders why I seem less than totally
critical of stupid things people do. I have to tell her I understand
that kids just do stupid things, they don't know any better and if
they're lucky and survive, they usually figure out "hey that was dumb,
I shouldn't do it again."

Wait until they get older and tell you the "war stories". :-)
