Bad behavior

I was truly appalled when i saw a small kid step on her toy with her mom looking on and not doing anything about it this afternoon. What is this. I know it's none of my business, but i cannot take this kind of behavior at all. If it's MY kid, i would have smacked her for misbehaving. I remember when i was about her age, i tried that trick and got some caning back home. I never tried that another time ever and i think a spanking will do her kid some good. She was screaming at the top of her lungs and the mother had her arms crossed and a big frown on her face. Damn, i felt like rescuing the toy there and then but i know i really shouldn't meddle with other people's problems. End of rant. Good night.
