We've probably all had the pleasure (not) of watching a timid, afraid to discipline parent trying to reason with their out-of-control, screaming brat-child in a store or restaraunt. As soon as I hear them speaking in that sing-songy "now sweetie, you don't want mommy (or daddy) to feel sad" type voice, my brain screams !! Of course the kid wants mommy or daddy to be sad, they want mommy to be sad enough to give in and buy them the toy or candy or whatever it is they want NOW !
"I'll give you something to cry about".
That usually shut me up double time, but if not, I got more than a spanking.
And thets nootttttthing wong wiv me!
