"You don't dare discipline anyone else's kids these days even when it's well deserved..."
Um, why not? For fear of getting a parent lashing? I mean, it's not against the law to scold someone else's kid, is it? If so, I want the proof.
I don't HIT other people's kids, no matter how much restraint I have to muster, but for God's sake, if a brat were to either hit me; [censored] on my floor and tell me to "eat it" while raising a finger at me; or bite my sleeve with or without a mouthful of chocolate, I would immediately impart the "It Takes a Village to Raise a Child" theory and disipline/scold the kid. I would and I have.
I am no more going to wait on a parent to do something they obviously should have done way before the kid got within my sight AND my home than I would wait on a knight in shining armor to rescue me if I were assaulted.
It's so nice that way in my circle of friends who have kids...they know that about me, and so do their kids. Perhaps it's why a) I have limited time with them and b) their kids behave like angels around me.
I think people who are bitten, hit or treated obnoxiously by a kid -- or if a kid does some kind of intentional damage to anything in their home -- those people are perfectly within their right to scold the kid.
