when I was a child, I was expected to behave with a certain level of decorum in public. Failure to live up to that standard was met with a response there AND at home. Sometimes it was something small, like being forbidden from watching my favorite afterschool cartoons for a week or two (and trust me...missing Speed Racer for two weeks WAS a serious punishment, the likes of which only needed to be meted once!) or bigger, like a time out for a particular time every day (I once had to sit in the corner for an hour every day for a week. BORING!) ANd if my parents dished out a punishment, it was followed through, they never merely stated a punishment and didn't carry through with it.
Before a punishment was dished out, I was always warned "stop it or else" and given a chance to cease with just a discussion of why what I had done was wrong.
I never misbehaved at Church. Ever. (Well, except for the time I gave the sunday school bully a black eye, but he took my hat and I did give him the chance to return it before giving him his punishment)
I didn't want children at my wedding because parents do not PARENT any more. Children are just that....children. But if they have not been trained with proper and respectful behaviour, and their parents do not bother to correct them when they act out, they why should I have to put up with the little blighters?!
