Sunset Shimmer was trotting around Ponyville, and found Twilight's castle. She opened the door slowly.
"Hey Princess Twilight, it's been a whi-" Sunset Shimmer said happily, but the rest of her sentence responded with a confused look. Twilight wasn't here. Instead, what she found was a light pink pony with purple hair, purple eyes, and a horn. Starlight Glimmer.
"What the? Um, hello, my name's Sunset. Perhaps you could tell me who you-" Sunset said, but Starlight Glimmer held a hoof up to stop her sentence.
"Sunset Shimmer, you say?? Well, Twilight has told me that she has a friend who lives in another world, but she said its best not to mention her to me or to mention where the portal was at because she still thought i was too, 'curious.' " Starlight said, looking at Sunset with a smile.
"Wait, you know Twilight?" Sunset said, as though no one else knew Twilight as good as Sunset did.
"Of course I do, I'm Twilight's pupil." Starlight said happily.
"Are you sure? I'm pretty sure Twilight would've mentioned you to me sometime." Sunset said, confused.
"Yeah, but then Twilight gets busy, and then she starts reading books, and then she has to solve a friendship problem, and then she's trying to assign me to solve a friendship problem, it seems she almost has no time." Starlight said, gloomily, and put her book down with her magic.
"Yup, that's Twilight." said Sunset, looking quite out of words.
"Well, since Twilight's not here, I'm pretty sure that you wouldn't want to be standing in her castle all day, doing nothing." said Starlight, and got up.
"Yeah, and i'm pretty sure reading books all day is really just Twilight's thing." Sunset said, and laughed.
"Heh, seems we both know Twilight really well. Well, since we're both here, bored, why don't we go outside and have a nice day? The breeze is just right." Starlight said, slowly opening the doors with her magic.
"Sure, I wouldn't mind hanging out with a friend." Sunset said, and walked with Starlight outside. Today is a nice day to be with a friend.
