Underwater Tea Party

Imagine that you went diving and happened upon a sunken ship. On this deck, you see a group of people in pre-French Revolution outfits having a tea party. What are those people doing there? Why are they partying on the sunken ship?

The prompt is also available on DeviantArt if you would rather comment there.
