Meeting your girlfriend's parents is horrible. Even in the best of situations it is an evening of judgement and trying your best to be as charming and inoffensive as you can possibly be. For Sunset Shimmer, it's made all the worse by the fact that she's a pony from an alternate universe, a former thief, and would-be conquerer of Equestria. Oh, and she turned into a winged she-demon that one time.
This shouldn't be...too awkward...right?
