While reading through the book I came across Basic Etiquette for a gentleman and a lady. I found it interesting the men's etiquette had to do with courtesy toward the woman, while the lady's etiquette dealt more with how she showed herself as being proper.
Reading the gentleman's etiquette a scene was conjured up on how my hero, even though he's been living in Lancashire England for two years, knows nothing of the etiquette and my heroine who is British but grew up a factory worker and just recently became a maid in a Viscount's manor, also knows little of the correct etiquette, will find themselves schooled by the villain.
These are the little tidbits that get me excited about a story I'm writing. I've found several others that I've envisioned using in scenes and soon the book will practically write its self. ;)
