Are you smarter than a 2 year old?

We went grocery shopping the other day, and as we were getting out of the car and heading into the store, Allie's prized sticker (one she pulled from the treasure trove of junk that seems to constantly litter the mini-van) blew away.

Allie: Where's my sticker?
Me: Oh, Allie, it blew away. We'll get a new one when we get home.
Allie: But where is it?
Me: It blew away.
Allie: But where?
Me: It blew into the street (in reality it was somewhere in the parking lot, but I wasn't about to start looking for it!) and we can't get it. We'll get a new one when we get home.
Allie: It blew away? It blew into the street? But, why?
Me: The wind blew it away.
Allie: The wind?
Me: Yes, the wind.
Allie: The wind blew it away, but why?
Me: Because a big gust of wind came and it blew away.
Allie: A big gust of wind blew it away? But why?
(after another 5 minutes of similar dialogue)
Me: I don't know why, Allie, it just blew away.
Allie: It just blew away? Why?

(Meanwhile, I'm wishing I'd paid a little more attention during junior high science class, as I ponder how to explain pressure systems to a 2 year old.)

Me: Because, it just did.
Allie: Oh.

With the "why" stage upon us, something tells me this is just one of many instances where I'm going to feel totally inept and incompetent at the hands of my child. For now, she is not aware of my total ignorance and is satisfied, for the time being, with "because".

(If anyone has some old elementary and junior high school textbooks lying around, please send them my way. I have some reading to do.)
