Why?

I have to say I understand the reasoning behind the why stage, but OMG! I dread saying anything to T. I just know that the next word out of his mouth is going to be why.... and that will go on and on and on. I am getting sick of answer the question, and he just doesn't let up.

And please tell me why because I said so is not a good answer to the question, or just do as mommy says.

Every time I hear the word why come out of his mouth I just want to yell, don't ever say that word again. I think that why is now considered a 4 letter word in this house.
