The paper reads:

You say to yourself, "I can't dance!". Well, I assure you sirs and madams that that is not true!
Please, join me in the fine art of dancing at 11am before the Masque. All are welcome to learn the basics of the waltz and ballroom etiquette with me, Professor Graftanimus. Partners are suggested but not required. It is highly suggested to bring comfortable foot wear with a flexible arch. Boots are definitely frowned upon in this case.
This event is free to attend and open to the public, and barring unusual circumstances, the venue will be at the tavern.
