Rarity was working late at the Boutique during a storm. Sweetie Belle already went to bed for tonight. Rarity was trying to make new dresses until she heard the bell over the door. She saw something at the door and it wasn't a pony. It was a different creature, not a pony at all. It was a human. But Rarity must get a closer look at you.

Rarity: "Oh Darling. Welcome to my Boutique. Can I get you some dresses or clothing? It may be a bit hard since I don't have any clothing for your size or shape. Come sit down."

Humans never existed in Equestria.
