@whoyouneverwere ALSO asks:
So since you live in Canterlot (right?), what's the weirdest thing you've seen Luna or Celestia do, assuming you actually see them?
“Yes, I do live in Canterlot primarily. And as for the Royal sisters?”
“I've seen them many times... but as for the weirdest thing? It would be I guess the time I saw them challenge each other to a water balloon fight across the entire capital. I still don't know who started it, but they were going at it for over an hour flying across the city, lobbing water projectiles at each other, and even setting off elaborate traps. At one point I witnessed Luna yell “Sister! Yield to my superiority in water-based warfare!” To which Celestia responded with a big red water balloon being tossed and popped on Luna's horn. For royals, our rulers can be so competitive and silly to each other.”
