"Twilight," says Starlight as she walks into the library of the castle, "can we talk? It's important."
"Sure, Starlight, what do you want to talk about?" replies Twilight as she puts a book on the top shelf.
"Uh, your behavior in front of the princesses. What you did was uncalled for. You don't give other ponies their personal space. You always cross their boundaries and you did that right in front of your mentor and her sister. What the hell Twilight! That's not how to behave in front of royalty."
"Yeah, I can see why you'd be upset about that," replies Twilight, "but do I really cross boundaries with everypony like that?" She puts another book onto the top shelf.
"Uh, yeah, you do," replies Starlight rubbing her neck nervously. "I've talked to Trixie about it, Applejack about it, the rest of the Mane Six about it, and they all said the same thing, well, except for Pinkie. They all think you get into their personal space constantly especially Trixie."
"Well," guffs Twilight, "well."
"You need help," replies Starlight. "You need to work on not crossing other ponies' boundaries because you'd never like it if they'd cross yours."
"Yeah, I suppose you're right," replies Twilight, "but how do I even stop?"
"First, we are going to Canterlot. You're going to apologize to the princesses for grabbing me and poofing away and being rude in general," replies Starlight as she firmly plants her hoof on the ground with a thud. Starlight pops the two to Canterlot.
"Princesses," says Starlight, "Twilight has something to say to you."
"Spill it Twilight," says Luna.
"I'm sorry for poofing off in front of y'all last week with Starlight. That was wrong. I shouldn't have done that," sighs Twilight with her head hanging between her legs.
"It's okay, we forgive you," reply the royal sisters in unison. Starlight and Twilight then say a nice and friendly goodbye to Celestia and Luna before popping back to the castle.
"See, that wasn't so hard," replies Starlight.
"I guess so," replies Twilight. "I just never thought I crossed ponies' boundaries. It never occurred to me."
"Now, let's go meet up with Trixie, Applejack, Rainbow, Rarity, and Fluttershy. They need to know that you're going to work on staying out of their personal space," responds Starlight. Twilight nods and follows Starlight to the cafe, where they meet up with their friends and take their seats. A few minutes later, Spike plops up onto a stool beside them. Twilight then gets to work on seeing how she gets into their boundaries and how she can prevent that from now on.
After two hours of talking, Twilight finally learns how not to cross her friends' boundaries. She's also taken it to heart and promises never to get into their personal boundaries ever again. Now, she's got to put those promises into action and that's going to be the hardest part of all.
