Nearly every time I go to the supermarket, I see parents taking the most ineffective, wishy-washy approaches to behavior correction I've ever seen, talking indirectly and halfheartedly to their children about how to behave in public. I hear them saying things like, "Okay, Brendon, you know, I don't think you should be fighting with your sister like that, it's kind of not the nicest thing to be doing" or "You know what, Jeremy? This whole whining thing you're doing? It's not really making me very happy."
Children don't respond to that kind of thing! I know I wouldn't have, at that age. You might as well tell your kids, "Do whatever you want, I don't care." When did parents start sounding like image consultants?! When did they start sounding like Lumbergh? When did they start being afraid to do so much as speak firmly to their children? What's wrong with a good strong "STOP" or "NO"?
