School of Friendship, Counselors Office
The Great and Powerful Trixie was most delighted to receive your letter, Princess. In fact, she doesn't know why you didn't reach out to her first! Everypony knows that Trixie loves to speak her mind.
That's why Trixie will tell you that your potion tastes wonderful. You should bottle it and sell it in stores.
Did Trixie ever tell you the story of how she learned her first magic trick? You see, one day, Trixie was sitting in the park, watching all the other little foals play. She didn't take part in such nonsense, because she didn't want to get her hooves dirty - her mother had just given her a hooficure, you see. While Trixie was definitely choosing to not partake in the shenanigans that were going on, a pony walked up to her, and asked her to pick a card.
Trixie humored him, and did so. She'd seen card tricks before, of course, and knew how they all worked - or so she thought. Somehow, this pony knew a trick Trixie had not seen. She was amazed - and immediately asked him to show her how he had done it.
He pulled a book from his bag, and told Trixie that if she promised to study everything inside of it, he would teach me the secret to the card trick.
Trixie promised, and the rest is history.
Maybe I will show you that card trick sometime, Princess.
I offered to show it to Starlight, but she said that she wanted to figure it out on her own. That's just the kind of mare she is - it's why I'm so fond of her.
I know I thanked you once before, but I wanted to thank you again for helping me find a home here in Ponyville. I know we haven't always gotten along (mostly my fault), but you were willing to put that aside for the sake of friendship, and to help Starlight.
A part of me will always miss the life on the road, traveling to new towns, wowing young foals. Being an illusionist is part of who I am.
But it's not the only part anymore. Another thing I have to thank you and Starlight for.
I lied earlier, as you might have guessed. I wasn't playing with the other foals because none of them liked me. My personality can be abrasive at the best of times. It works for a showy magician, but not so much when it comes to making actual friends.
But that's the old Trixie. I'm not that mare anymore.
Starlight and I are planning a vacation soon. We want to go visit a few places once the School lets out for summer break. I know you're busy these days, but I want to invite you to come with us for the day when we stop by Canterlot. I'm putting on one last show, you see, and I think you'll enjoy it.
If you come, it'll be for an audience of three, rather than two.
If you're too busy, I understand. Trixie is nothing if not resilient.
But I'd really like it if you came.
Cordially, Sincerely, With Love,
Trixie Lulamoon.
P.S. The potion tasted like dishwater.
P.P.S. Do not ask me how I know what dishwater tastes like.
Princess Twilight told me that the magic show was spectacular. She also confirmed that Trixie returned to speaking about herself in the third person once the potion wore off.
