I'm paraphrasing of course…. this is how it really went
Twilight was worried about her young student Morning Atlas, he spent too much time holed up in dark library's and dusty achieves. He reminded her of herself when she was that age, no friends and no time to spare. Except Atlas was a bit less " soft spoken" to put it, as she once was. His busy schedule wasn't the only reason he barely had any friends. So Twilight was going to take a page from her old mentors book, and was going to send him down to Ponyville. Put him in charge of the library there, and make him write down everything that happens and the lessons he'll (hopefully learn).
Atlas entered the Grand Hall with a his usual scowl, upset at anything that interrupts his studies even if it was the ruler of Equestria .
" Atlas, Thank you for joining me this morning, the day is looking bright isn't it"?
"Cut the small talk, please, you said this was important and I'm busy". " I have a new project for you Atlas, Your going to go down to Ponyville tonight and look after the library".
" You've got to be kidding, I already have so many other thigs to work on, I don't have the time for this " !
" Well, we'll be pressing pause on your other assignments for now, what I want from you is to focus on this new task. I want you to go down there, makes some friends, learn about the life there."
" What are you talking about, for Celestia's sake this is pointless, I have much more important things to do than, make friends with some small town, earth eating ponies from Ponyville."
" I've obviously failed to teach you some important lessons, but hopefully going to Ponyville with fix that. I will not be giving you any more projects until your finished with this one, it's the most important one you will be learning. I'm not asking you to go to Ponyville, I'm telling you to. Please."
" Fine, I'll complete your little task, and I'll learn your little lessons about friendship. And I'll do it quickly so I don't waste too much time, and I can go do some actually important things."
" Oh, and you taking Northstar so you don't scare away anypony"
