You did create monsters!!! My mother had a great rule she passed down to me. Never do anything more than once that you don't want to live with for the rest of your life.
I live by that rule!
Still, smashing rocks is a bit fun when you are their age! :)
I will remember that rule! Not saying I will be able to follow out but I will remember it!!
It was the only way my mom could keep her 9 children in line. Being consistant.
I ask you, where is the fun in that?????
