Why the door?

So my kids have been on a little temper tantrum kick lately. Really a KICK! They have been testing... "what will mom do if I... Kick the door down?" Also the "I wonder if I can actually kick my bedroom door off?" Well they are trying. But NO they aren't quite strong enough to kick it off or "maybe Mom doesn't wait for that. She puts me in timeout every time. Man I thought I'd get away with it!" Needless to say I think they must be fighting this cold they have and are really extra tired lately. I know they love having their bedroom door attached or maybe they don't..., we'll see when they turn 13!
