if green should turn to grey...

Here's what I got on the way home today from K.

"Mommy, what if someone ripped off the sky?"

"Uh, what do you mean?"

"You know, just ripped it off from the earth, so there wouldn't be a sky anymore...we wouldn't be able to breathe, would we?"

Aren't kids supposed to ask, "Mommy, why is the sky blue?"
