Dear Princess Celestia,
Hello, Celestia. Don’t worry, I’m not going to take Twilight out of your school. I know that you will care for her. But there are things we must discuss, away from her ears. We’ve known each other for too long for me to think you’re perfect. You make mistakes, same as any pony. Here are some you should take care to avoid. That is not a threat. It’s a plea, from one friend to another.
One, keep her thinking. Too many ponies are blinded by you. They stop asking questions, stop thinking about the possible ramifications of your choices.They become nothing but zealots for your cause. This is not your fault, and I know you agree that we must always have ponies there to question you, to keep you in line. I ask that Twilight be one of them. She’s always marveled at you. Admiration is alright. But always remind her that you are not perfect, that your word is not law. I will not have my daughter be a drone of the Princess.
Two, keep her safe. You have enemies, as any pony of your caliber would. Some may target her. Please, protect her, without impeaching on her freedom if possible. She is my and my husband’s world. You know how much I value self-reliance and strength, of overcoming tragedy, so I trust you will take it seriously when I say that I do not know how I could live without her.
Three... This is petty of me. It’s overemotional, weak. But, please. Don’t take my place. I know we’re allowed to visit anytime, that she will be sent here extremely often, that we can always keep contact, but the fact remains that she will be seeing more of you than she will see me. And you are amazing, my friend. Though we may not always agree on everything, never doubt that I do believe that. And as I said before, Twilight adores you. You will be teaching her so much, not just magic but life lessons as well, and that frightens me, as pathetic as it sounds. How can I compete with the idol of every filly? How long will it be before she subconsciously calls you mom, even if for a split second? How long before I come second to you and become an occasional visitor who babbles about a home and matters that she barely remembers? It is selfish of me, and I apologize. But please. If you could keep some distance, some professionalism, something...
Bah. Forget that last passage. You don’t need to hear that. What matters is training Twilight to the best of her abilities so that she can better service Equestria. If that requires you two to get close, then that is how it is. You should not bother yourself with the prattle of some sappy mother. Don’t tell Twilight of this. You know how much she hates ponies thinking she can’t take care of herself. Or you will know, in any case. You are a good Princess, Celestia, and far more importantly, a good pony. I trust you will do what’s best.
Your Friend,
Stardust
