Haha! My friend's mom popped her nephew in the mouth in the checkout line at shopko. He was like fourteen, though. He looked at the cashier like she was going to say something, and she said, "I bet you'll think twice next time you wanna get smart" LOL!!!
I told her she should be careful, though, because her husband was a senator at that time, and the media would have a field day with that one. Kids are just really disrespectful, and I think sometimes a good swat is in order. My dad used to slap us in the face once in a while, but my current pastor said that he would never hit his kids in the face because there's a humiliation factor that isn't really necessary. He said that's what the backside is for. I agree.
