(deep in discussion about life, the universe, and everything)
Four-year-old daughter:  So the sun shines somewhere else when it goes away from here?
Mama: Yes.  Our planet moves around the sun so everyone gets a chance to see it.
Four-year-old daughter:  That's so exciting.
Mama:  What is?
Four-year-old daughter: That the sun eventually shines, even in the really dark places.

(Daughter has just knocked over a water bottle, which she quickly caught.)
Four-year-old daughter:  It's okay!  I was a total ninja!

four-year-old daughter (talking to her doll):  Okay, Dora, that was more like a game of seek.  Because that time you weren't good enough to hide from me.
