On a quiet hill outside Ponyville, there are two trees side by side. One that butterflies flutter around, and woodland creatures bask in the shade of. And another that if you watch closely as the sun rises and sets, seems to glow.
Every year a mare with a white coat, pink mane, and a cutie mark of a sun obscured by rain clouds sits beneath the second tree and reads a letter.
A simple letter, written by a foolish mare.
A foolish mare that life will never be the same without.
