To tell the truth, for me the appeal of the Regency Romance Genre is something like:
-5% a single man in possession of a good fortune
-35% pretty dresses and bonnets and parasols
-60% a society with actual codified rules, that everyone knows and is taught, and never having to guess what the appropriate thing to say or do to not get labeled a Weirdo Who Can’t Have Normal Conversation. I would ROCK an interaction where I had a specific list of topics and duration of time, underpinned by how much I am allowed to share or not share about my personal life based on our relationship.
