>I know someone who simply CAN NOT grasp that if they let their kids make a mess, that it's actually THEM making the mess. They can't grasp that they're LETTING the kids make the mess and therefore really making it themselves by proxy I know the type. "i gave my child candy to get them to stop screaming". Oooook retard, if only you realized you just trained your child that screaming is *rewarded* >Another is I've noticed people who simply can not understand the idea of scale. I know the type. "This item is only $15, I'll put it on my credit card and pay 30% interest on it. It's not that much!" Sure, $4.50 of interest is peanuts in the grand scheme of things. BUT the 30% interest on the $15,000 credit card debt you already racked up through similar onesy-twosey purchases is approaching a mortgage payment every month. So many people do this.
