A guick anecdote:
Yesterday after work I was in the back yard playing with Zoe. It was daytime still, but we could see the moon. Zoe has long since enjoyed seeing the moon. So I told her to try to jump up and grab the moon. So rather than go through all that trouble, she opted to stretch her arms up towards the moon and scream "Com'ere moon!!!"

I told her that maybe one day she would reach the moon.
