I wish more parents would do things like that. Just the other night I saw a report about a restaurant owner who would walk up to parents who had kids that were misbehaving (who weren't correcting them) and ask them to please make their children behave properly in his establishment. He would ask them nicely to do this, then if they didn't...he would nicely ask them to please leave because they were disrupting the pleasant dining environment he had worked so hard to create for his patrons.
Now, I know some people would have been terribly offended at what this Chef/Owner did, but I admired him for it. I also admire parents who correct their children when they are misbehaving and address the situation.
Now of course your wee ones weren't doing what some of the kids in this report were...what yours did is something I could see Ian doing LOL. They weren't being little monsters...just precocious kids....but you still made them own up to their behavior! What a good mom you are!
