Luna: Oh! A sundial. How thoughtful of thee.

Celestia: I knew you would love it!

L: Thank thou fort his gift, sister.

C: Do you how special is this one?

L: No. I have no clue.

C: Come on. Guess.

L: I... This one actually shows time?

C: Not even close. This is one is made of brass!

L: Oh.

C: ....

L: What can I say...

C: You don't seem to enjoy it...

L: Huh? Oh! But of course, of course! I... I'm putting it on my dresser by my Moon Clock.

C: Moon clock?

L: What? Can't you see it?

C: Uh...

L: It is very special magic clock that works only at night. The fuller the Moon, the brighter it become.

C: Um...

L: Oh! It is hard to see for the neophyte eyes.

C: Something tells me you are lying...

L: What? Me? I love your sundial! Now, if you excuse me....

Luna left, followed by her sister. Later, after Luna raised her Moon and left for her nocturnal duties, Celestia sneaked in her bedroom to check on the "clock".

C: I am no neophyte about magic and yet I can't see no Moon clock! I wonder what time it is...

Suddenly from a corner.

L: It is time to get yourself a clock, sister!

C: Gah! Luna! What are you... Wait!

She shifter her gaze at the top of the dresser where her gift lied.

C: There is no Moon Clock, isn't?

L: As there is no sundial for the night, sister.

C: .... Maybe if you try with the moon light....

L: Go to bed, sister.
