It's like the parents that are unwilling to come down hard on their three year old for being a shit head.
Oh, my three year old tried to stick a screw driver through the protective grate of a fan... THAT WAS RUNNING. Nah, don't reprimand them or anything just go "are you turkey?" and when she giggles and goes "yeah" just go "you're a beautiful princess" or some bullshit.
I went to do that my dad would have LET me put the thing in the fan and get fucked up. "Well, you won't do that dumb shit no more now will you?"
