My generation had “Ms.” which became mainstream in the 60’s.
Everyone has adapted.
Society made it normal.
And the World continues to turn.
Amazing.

“...the default use of Ms., especially for business purposes, is championed by some American sources, including Judith Martin (a.k.a. Miss Manners). Concerning business, the Emily Post Institute states, "Ms. is the default form of address, unless you know positively that a woman wishes to be addressed as Mrs." The American Heritage Book of English Usage states, "Using Ms. obviates the need for the guesswork involved in figuring out whether to address someone as Mrs. or Miss: you can’t go wrong with Ms. Whether the woman you are addressing is married or unmarried, has changed her name or not, Ms. is always correct."
