Author's Notes:

Letter 1: Here

To my most faithful student, Twilight Sparkle,

I have received your missive and friendship lesson courtesy of Anon. I'm glad to hear Spike has decided to explore his options as an Equestrian Citizen, and will ensure I keep in touch with him for you. I admit I am proud of you for trying to make Anon feel as though they fit in by giving them meaningful tasks, but perhaps you should make an effort to write me yourself on occasion. I do miss your direct contact from time to time.

As per your friendship lesson... that is a very important lesson indeed. We may not always succeed in putting our best hooves forward, but it's important to acknowledge our mistakes and make amends.

Your loving mentor,
Princess Celestia.

PS. It's nice to see you are adjusting to your life in Equestria, Anon. I appreciate your razor whit and most esteemable and eloquent conveyance of the pleasure of your current position. I know I sometimes feel your own difficulties equally.
