My Little Pony - Twilight Sparkle and Princess Luna
"Dear Princess Celestia,
While it's always important to remember to study, there are other things that are just as vital to remember: An inner life is nice to develop and flourish...but there is no greater world than the reality where you know you are loved and cherished.
Your Faithful Student,
Thine precious student dost hath a fine flank.
Haaaaa. I'm funny.
But seriously, I drew this as a distraction. I'm not feeling too well to do anything important, and needed to relax. No idea why ponies came out, though. But oh well, who am I to turn down Twiluna?
