In Hollywood people give their personal pronouns when they introduce themselves. No he and she for them. I live in Tennessee. My personal pronouns are Leave me alone and Get the hell out of here.
I'm sticklish on correct pronoun usage. I hate hate hate to see or hear a plural pronoun -- them, they, their, themselves -- used for a single person, e.g., "The other driver wouldn't give their name." People who misuse pronouns thus debauch and uglify the language. Sure, they have a right to do so, just as a person has a right to keep garbage in his yard, or to tramp stamp her body from wrist to ear and put a bone or a bolt through her nose. But it's ugly, and the rest of us have to look at it.
I like to died (look it up!) the first time I read Philippians 2:3 in the KJV (1611): "...let each esteem other better than themselves." Ugh!
They should have stuck with Tyndale (1534) on that one: "...every man esteem other better than himself."
When I was a corporate slave, I always addressed a woman I didn't know as "Mrs. So-and-so". I figured I would be right about 85% of the time. I was almost certainly wrong sometimes, but interestingly, no woman ever corrected me. But that was 15 years ago; I'd probably need to wear some good noise-cancelling earmuffs if I did that today.
