Nor would I have gotten away with it...my rear end would've been sufficiently "tanned", and was...on a few occasions.

Thing is, in today's world, you can't do much. You can end up arrested.
My niece diciplined her daughter just a few weeks ago.
The two girls, 9 and 6, were fighting and having a pinch fest.
Each blamed the other for starting it, when it was the 9 year old in the end who really had pinched first, but she blamed the 6 yr old sister.
So my niece pinches them both, as punishment for pinching.
The 9 year old jerked her arm away, when she did, my niece only caught a tiny bit of the skin and it left a little bruise.
Well, her ex-husband, the father, turned her in to Child and Family Services, the Police came, all the children who were present were individually questioned (privately) away from the others. The case still hasn't been closed.

My niece is also a school teacher, kindergarten, if she gets charged with anything, she'll lose her job...which is the goal of the ex. It's all really ugly...but, my niece knows better.
I mean it's a very sad world that you can't pinch a pincher, who woulda thunk.

But not anymore.
My other niece grabbed the collar of 13 year old and marched him to his room when he mouthed her one day. She grounded him...and he called the 911 from his room after she went back to the kitchen.
The police showed up, said he'd reported that she "man-handled" him.

She didn't get in any sort of trouble, but yeah...that's the kind of stuff that can happen.

Not like the old days when we were growing up.
