When I was a boy of about 13 or 14, we would have to take a civics class in school . One of the many topics in that class was how to address government officials . For example "The Honorable so and so..." if they were a Governor of a State or " Mr. or Madame Secretary" for those that occupy cabinet positions ie. Treasury , State, and so on.
Do you guys have similar studies except specifically in regards to how to address members of the royal family ? Dukes , Lords, Ladies and what not ?
Just curious...brought on by a discussion 'tween the wife and I.
