I understand what Doc is saying. I wouldn't call it "dumb" but perhaps a bit inexperienced. You can dare a child to call the police, and say what you would do and all that, but the fact is that when it happens, it's a whole other story.
I've told some of you about the time my daughter put makeup under her eye and told her guidance counselor I gave her a black eye. The short version is that she had developed a close relationship with this counselor and it gave me some sense of relief. Then one day, the lady asked if my daughter could spend the weekend with her. I thought that was inappropriate, and if nothing else, a little weird. I wasn't comfortable with it, so I said no. That was the beginning of a pretty rough chapter. My daughter had a fit and a week or so later, pulled the fake black eye thing. The police were called and social workers came in. The only thing that "saved me" was that I told her she better know what she's getting herself into because when this is all said and done, she'll be living in foster care. She started crying and the makeup started to run down her face.
The fact is, if they call the police, you can be pissed enough to want to beat them, punish them, take away all their luxuries, send them to state custody or whatever, but that doesn't change the effect it can/will have on your life... so yeah, dare them to call, but know that it'll still cost YOU either way.
