Oh so smart

Abby and I were cuddling in her bed after reading books last night and out of the blue we had this conversation:

A: Mom, people live on Earth right?
M: Yes.
A: And we're people and live on Earth
M: You're right.
A: There are other planets right?
M: Yes there are. Lots of them
A: But no people live on those planets do they?
M: Nope, just on Earth
A: How come?
M: Because our planet is special
A: Okay. And this is called the whole world right (spreading arms around again)
M: Yep, Earth is also called the world
A: How big is it? This big? (arms far apart)
M: Bigger
A: This big?! (arms farther apart)
M: Even bigger
A: This big??!! (arms as far apart as they go)
M: It's bigger than your arms and my arms can reach
A: Wow Mom, that IS big!
M: Where did you learn about planets from?
A: I just learned it in my mind
M: Any other questions?
A: No, that was it.

It's always fun to hear just what her little brain is pondering. Jerry and I figured out that she must have heard about Earth and whatnot from watching Space Monkeys the other day. Everything you know you learn on tv, right??!
