Cuz So

Each time the question "Why?" is posed to Hannah or Leah, the response is "Cuz so."  Leah why are you pulling your skirt up to your chest?  Cuz so.  Hannah why did you shove half a burger in your mouth?  Cuz so.  Leah why are you drinking the bath water?  Cuz so.  Hannah why are you sucking your thumb?  Cuz so.  (real question to that should be something having to do with us taking away her pacifier or something to do with the fact that her sister sucks her thumb).  I believe the response Cuz so is derived from the longer response I frequently use "Because I said so".  I will have to find a new response.
