But I read the OP's original post on this topic... and that seemed to be his aim.
And it has seemed to be the aim of every single spanking I've ever been party to or witnessed either in person or in the media.
Making the child hurt, react, cry out, leave a red mark, shed some tears... whatever.
What about the kid who does NOT react to the smack?
Was it the smack, or the child?
I'll give you two guesses what the reaction of the spanker is in that situation BTW.
*Hint: It's definitely not "Oh, OK... you've already been punished so you're done." At least not IME.
