My faithful student,
My, how time flies. One week since you left Canterlot, and no panicked letter requesting my aid? You must have things under control...or you're resting in a straitjacket. It better not be the latter like last time.
Anyway, it just occurred to me that you might be homesick. I mean, I did send you away from Canterlot rather suddenly and almost without notice, so I hope you squeezed in a goodbye to your parents before you rode that balloon out of town. If not, well, I'm sure you left them a letter or something, right? A post-it note, at least.
But regardless if you did or not, I put a surprise in this letter for you. Enclosed are two tickets to the Grand Galloping Gala. You know, the big celebration where a ton of noble ponies kiss my hooves until they prune over. One's for you, and another is for a friend you can bring along.
I sent just one extra because I have no idea if those five ponies you made friends with are just acquaintances or the real deal. Yes, I know they helped with Luna, but anyone can be a hero for five minutes. It takes far longer than that to show good friendship.
Choose wisely, Twilight. There's a reason these tickets are golden and not onyx. No, really. Luna's getting some new regalia fitted for her and demanded ALL the black onyx like it grows on gem trees. At this rate I'll need to renegotiate with the Dogs again, and that never goes well.
I'll see you at the Gala. And remember to dress modestly; sticking a ruler and a bookmark in your hair doesn't count as "classy" attire.
Love,
Princess Celestia
