WHY?

Noah's new word......Why?. It comes after almost everything you say to him and again and again. It is usually finally finished with an OK. Here is an excerpt from our recent conversation why the 3 of us were driving to daycare.
Noah: "Mama balloon broke." (we had been at a festival. The local karate place handed out balloons attached to sticks- ours was no longer attached to stick)
Me: Yes, it's broken
N: Why?
M: Because
N: Why?
M: Because it fell off the stick
N: Why?
M: Because it is a cheap balloon
N: Why?
M: Because they could not afford better balloons
N: Why?
M: Because we are in an economic recession.
Noah: Okay.
