The moon

Last night Ellie and I were driving back from my sister's and there was a full moon in a clear sky.  She struck up this conversation:

E: The moon is following us
Me: Yes, the moon follows us
E: Silly moon
Me: Yep, silly moon
E: We take a rocket ship to the moon
Me: (Surprised) Yes, we have to take rocket ships to get to the moon
E: In outer space
Me: (Again, surprised) That's right in outer space
E: And we float!
Me: (Where is she learning this stuff?) You're right Ellie, we float in outer space because there's no gravity
E: Yup!

Ok, note to self, there's way more going on in that little than I could ever imagine.
