Derpy Hooves, the mailmare of Ponyville. The only mailmare of Ponyville, to be exact. She knows every letter and package that is sent, and she knows who gets a lot of mail, and who doesn't get anyhing at all.
Rarity seldom gets any mail, and now, somepony is sending her love letters. Somepony who doesn't give out their name.
Derpy follows the affair at a safe distance, hoping that one day, the anonymous pony and Rarity will find each other.
And until that day, Derpy will do her delivery route, as she does every day, sunshine or rain.
Just a quick sweet thing, written in like one hour. Now edited with the help of Psi-nova! Thanks mate!
