Letter from a Disgruntled Friendship Student: Filli Vanilli

I came up with quite a bit of material for this one, and after letting MilesPrower have a crack at it, I threw this together.

Dear My Five Closest Friends,

It’s understandable that you wouldn’t figure out I have stage fright, it’s not like you could infer that from pretty much every interaction we’ve ever had. And before you fire back at me with a bunch of statistical outliers, Twilight, would you be so kind as to explain to them what a statistical outlier is?

Sincerely,
Fluttershy

Dear Everypony,

A statistical outlier is moment that’s so unusual that you ignore it and instead look at the more common occurrence. And as long as we’re playing dictionary, "a capella" means without instruments.

Just saying
-Twilight
P.S. Hey Rarity, that's two things your sister is better than you at: Singing and being a dictionary!

Dear Everypony,
Incidentally, does anypony have the adoption papers that the new pet owners filled out? I assume that somepony took care of the registration and background checks, and that you didn’t just let the crowd take my animals indiscriminately.
-Fluttershy

Dear Diary,

Gaegogi es muy delicioso!!!

Sinceramente,
Zipperwill

Dear Fluttershy,

I’m super super duper glad you have your old voice back! It’s soooo cute, and it just makes everypony’s heart melt! Now, a mare with a dikey tenor voice? You’d never get a herd of horny colts chasing after that!

Sincerely,
Pinkie Pie

Addendum: Sorry about this Fluttershy, I couldn’t intercept it in time. We love you no matter how your voice sounds.
-Twilight.

Dear Zecora,

Got any more poison joke?

Sincerely,
Fluttershy
