Roadfood: Judith Martin, a.k.a. Miss Manners, is a journalist in the Washington, D.C. area, with several decades of experience on Washington social events, including those frequented by political leaders. You need not accept her authority, as I said above, but to suggest that this subject is not within her purview shows an ignorance of her body of work. (More info here: Wikipedia on Judith Martin) I wouldn’t mind seeing a cite from a better authority, myself.
For what it’s worth, protocol and etiquette are not unrelated. They are sets of formalized rules of human interaction ultimately based on customary behavior in a given society or segment thereof. One is for social functions and the other for government functions. I like the way you trivialized the whole concept of etiquette with the fork example, though.
According to [post=9121079]this thread[/post] where the topic of how to refer to the husband of President Hillary Clinton was discussed, Bill Clinton should properly be addressed as “The Honorable Bill Clinton”, not as Governor Clinton or Former President Clinton.
This puts me in mind of a whole (short) series of poems. From the fortune files:
I never saw a purple cow
I never hope to see one
But I can tell you anyhow
I'd rather see than be one.
-- Gellett Burgess
I've never seen a purple cow
I never hope to see one
But from the milk we're getting now
There certainly must be one
-- Odgen Nash
Ah, yes, I wrote "The Purple Cow"
I'm sorry now I wrote it
But I can tell you anyhow
I'll kill you if you quote it.
-- Gellett Burgess, many years later
