A Second Chance at Storytime by NewportMuse

: (very nervous and embarrassed) So uh, yeah, Twilight... during my magic practice I decided to try this temporary age-reversal spell on myself, thinking it was just for 30 minutes. But I misread it and cast a Duobus Diebus instead of a Tempus Momentarius. You know, all those Latinus rhymingus wordus. So now I'm... (lowers head) stuck as a filly for the next 48 hours.

: (stunned) ...

: (then smiles warmly) Oh, Starlight... I can see how all those similar sounding words can mess you up. That happened to me back at magic school. (giggles) But you so look so cute as a filly.

: Really?

: And, take a look at your flank.

: (looks at her flank, then squees) EEEEE! I STILL HAVE MY CUTIE MARK?!? Hnnnnnnng!

: You're still the talented Starlight Glimmer who is my pupil and friend. You just so happen to be temporarily stuck in a foal's body. Even the most talented ponies make mistakes.

: Yeah. Even Trixie told me that once.

: Just like me, Starlight, you've been studying a bit too hard. You need to just rest for while. So instead of you reading a book, I read a book to you! (floats a storybook from a bookshelf) What was your favorite story as a filly?

: Twilight, are you serious? (laughs) Okay, Ponylocks and the Three Bears.

: That's a good filly. Just relax, rest and listen to Aunty Twilight. (begins to read) Once upon a time in the Everfree Forest, there lived three bears...

And so Princess Twilight Sparkle teaches her newly de-aged student Starlight Glimmer how to make lemonade out of lemons. As long as she is stuck as a filly, Starlight can have the fun that comes with it and enjoy being young again until she returns to normal. Everypony makes mistakes, but we should never beat ourselves over them and hold us back from making a new start.
