(This is an old story I wrote three years ago during season 1)

Twilight Sparkle's birthday has come around, and Rainbow Dash is unimpressed with Rarity's present. When Applejack pokes a bit of fun with her friend, Rarity becomes unusually upset. Twilight Sparkle investigates her friend's feeling, learning something she never expected about her friend and why she is truly suited to be the element of Generosity.

Short story inspired from an amazing picture by Harwick.

Long years have passed, and Twilight Sparkle has outlived most of her close friends. As Twilight's time in Equestria draws to a close, Princess Celestia teaches her student a final lesson filled with cosmic revelations. (And yes, it does actually have a happy ending.)
