The first story in The Retirement Series, a collection of comedies about what Celestia and Luna do now that they no longer rule Equestria.

If there's one thing you should know about your sister, especially if you are both thousands of years old, is what they don't like to eat. It seems, though, that over the years, Luna has forgotten one detail: Celestia doesn't eat spicy food. She doesn't remember until it is too late.
