To my most faithful student, Twilight Sparkle,
I would be admittedly very interested to see your work on the subject whenever you consider it ready for review. Anon admittedly curtails his slang and euphemisms to a degree when in my presence, so I doubt I've borne witness to the most interesting or colorful variants.
Come to think of it, does it not strike you as odd that our languages are compatible in the first place?
Your loving mentor,
Princess Celestia
Dear Anon,
Today I noticed Twilight wrote me a letter, either by herself or penned by Spike.
I just wanted to check in on you.
Your friend,
Celestia.
