With one simple statement coming out of my mouth, it can lead to 20 “Why?” questions from my daughter. 
A conversation I just had with Rachel:
“Who was that?”
“It was Daddy.”
“Oh Daddy! What’s he doing?”
“He’s working.”
“Why’s he working?”
“Because.”
“Why because?”
“Because his boss says he has to be there from 8 o’clock to 5 o’clock.”
“From 5 o’clock to 8 o’clock?!  Why?”
“Because that’s just how it is.”
“But why?”
AAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!  Does this question just automatically hit when a child turns three?!  If only I had a dollar for every time the word why has come out of that child’s mouth, I would be a stinkin’ millionaire already!!!
And just as I'm finishing this post, Rachel calls from the stool “Why’s he at work?  Why?  Why?  WHYYYYYY?!”  Oh my LORD!!!!!!!!!!
