Author's Notes:

Last one for tonight.
Letter 58: Here.

To my faithful student, Twilight Sparkle,

I think this is one of those things specific to Anon's origins. From context, I would assume this to be an Anonism for 'She is adorable and must be treated with affection and indulgence, rather than inappropriate behavior' but I may be missing some subtext.

Your loving mentor,
Princess Celestia

PS. Anon, who is Hansen?
