Masked balls are fascinating events. Masquerades really became popular in the 15th century, when a mad, but perhaps more genius, king who crashed his own party, and promptly managed to set his outfit on fire.
The spectacular portion of such a ball is how you are able to talk and communicate, but be able to leave any baggage behind. Assuming that you have a really good disguise, or that everyone else is half blind, of course. You can interact, learn, and delve into others, while being perfectly free to let yourself spill over. Nothing really matters, you are just learning for the sake of learning. There is no conclusion, there are no consequences.
Wouldn’t it be interesting to be completely anonymous?
