Why?

Cameron's discovered the word WHY? I'd heard tale that children go through this stage, but until actually experiencing it I never really understood the frustration. Its only been about a week so far but man I can definitely understand the phrase's "Because I said So", and "Because I'm the MOM that's WHY". I mean how else do you explain "why", no more marshmallows, when you have exhausted all other reasonable and rational explanations. All I can say now is that I hope this is a short phase, until then I just keep up with the "Because I'm The Boss!"phase.
