WHY????

The Boy is three. This means his favorite question is, say it with me now, "WHY?"
He says this any time a parent, usually me, talks to/with him about anything. Including the following:
"Boy, please pick up your toys."
"Boy, please wash  your hands."
"Boy, Mommy thinks it's potty time!"

Words cannot express the level of my done-ness with the word "why".
Until last night.
Late last night I was up with The Baby and I heard the boy talk in his sleep. He only said one thing, but he said it loudly,


  "WHY?!"


I am not sure why this funny, or even why it's STILL funny nearly 24 hours later, but trust me, I'm laughing out loud. Seriously. Out loud on the inside, anyway. Everyone's sleeping.
