(So many of the things I’d want to ask Celestia would be obvious to a visitor to Equestria but not included in the series and not things I want to burden CS with. Well, I’ll try this one.)
 
Are there griffons serving any of the Princesses officially, and if so what kinds of things do they do?

Do you know of a pony named Starlight Glimmer?

Have you ever been in love in anypony?

Do you have a crush or special somepony? :3

Oh my goodness, I just realized that the “Chocolate Explosion Cake” I ordered is far bigger than I realized it would be. It’s got five layers of chocolate cake with chocolate icing on the outside and between each layers, served with 3 scoops of chocolate ice cream and lots of hot fudge. I can’t POSSIBLY finish this all by myself… Want some?

What are your thoughts on Nightmare Night?

Do you and Luna ever get time to keep up with modern music trends in Equestria?

How are you and Luna today

Does Celestia’s Servant regularly stalk you? :^)

Have you been feeling overworked lately? I’m a little worried for you.
