Ah, yes...embarassment. A great tool in the right situation.
My son learned early on that if he misbehaved in WalMart, I just might break out into song and dance in the aisles, just to draw attention to his bad behavior and his crazy mom.
Never had much problem with him in public, imagine that.
Good job! The difference between embarrassment and letting your kids smoke, drink, and do drugs, is that your kids won't die from embarrassment. We aren't here to be their "buddies", we are here to be their parents. Embarrassment isn't abuse, it doesn't cause trauma and it definitely won't kill you.
