Child of the Moon

Luna: Tia! Tia!! Look! I'm the mare in the Moon.
Celestia: *giggle* Good one Luna.
L: Hey! Do you think that one day we could walk on the Moon?
C: Why we would do that?
L: Well, so somepony would be say "Hey! I walked on the Moon. Jealous?".
C: I don't think that Mother would allow us to use magic for something like this.
L: Really? Aww...
C: But... What if you could raise and set the Moon?
L: Why me? I like the Sun. It's warm and make you happy.
C: Luna! You can't like the Sun because I like it!
L: Heh? What's wrong with that?
C: You keep complaining it gives you sunburns.
L: W-welll.... I-I would adapt.
C: *giggle* Seriously. What if you were the one who controlled the Moon?
L: I.... I don't know. I would miss the day?
C: True.
L: But.... If that would allow me to go walk on it... Yeah. I'd love that! *smile*

Many centuries ago.
C: *sniff* And we were only joking about this... I hope you can walk on it now...

Beautiful work
