Either Ms. or Mrs. is fine. I really don’t care. It’s surprising how often retail workers, waiters, etc. call 45 year old me Miss though - I suspect it’s a self defence mechanism engendered by people being stupidly offended at being identified as older than voting age :rolleyes:
I don’t care for Mrs. because I am also chronically single and what bothers me about that is the default assumption that anyone my age IS married. It’s a reasonable assumption because most women my age are married, but a lot are divorced. You really shouldn’t make assumptions, so it seems to me that Ms. should just be the default and then you don’t have to look for a ring or any other physical clues that someone might be married.
Typically, if the situation is so formal that someone uses a title and my last name, it’s also probably not terribly appropriate to correct that person. Hell, I don’t even correct the plumber if he calls me “Mrs. Zilla.” Whatever. It’s not that big a thing to me. I’ll spend 0.00003 seconds being slightly annoyed at the default assumption (that of course I’m married, because everyone is, right?) and then will go about my day. Bigger fish to fry. Gave my last fuck at the office.
Ms. Always. I am unmarried, but in my 40s and in a long term, live-in relationship, neither Miss or Mrs are appropriate.
It drives me crazy how often I’m asked ‘is it Mrs or Miss’, and I have to correct them with a third option. Come on people, it’s 2016!
Dr., please, if its in a professional or formal context.
Ms., otherwise. Mrs. is inappropriate because I didn’t change my name when I got married.
‘Miss’ is ridiculous for anyone over 10.
Doesn’t matter to me, though being called “Mrs.” makes me giggle because when I was a bratty adolescent I used to refer to my mom as “Mrs.(our last name)” so now all I can think of is her laughing from The Beyond and saying “*who’s *Mrs.__________now!”
What about her husband? I assume he was equally proud, yet was left with no way to be labeled as ‘husband’. Tragic.
I’m with Nava - I’d prefer not to choose one at all, but I’ll go with Ms. if I must.
Or spinster daughters of the Confederacy, and then used with their first names, but I think they are all dead now.
Right–the ones that would have transitioned to “Mrs. Harvey Brown,” had they married.
I voted (Ms.) on my wife’s behalf. We see eye to eye on this.
When queried, my female associate reported preferring to be addressed as Dr. for situations requiring a title.
You’d be surprised. I get a ridiculous number of (college!) students who address me as “Miss Firstname” and a few who, at least, manage to get my professional title right and call me “Dr. Firstname.” (And honestly, I would be fine with my students calling me by my first name and no title, but that’s not the culture here, and the weird alternatives they come up with drive me up the wall.)
The default was to be called ma’am when I was in the south, and now I live in a place where the default is “Miss”. I’m ok with either, or with Ms, unless you know my title and it is a professional/adult setting, then use my title. Also, no Mrs.
Voted Ms. Didn’t take my husband’s name when we married.
Yeah, I know - grew up in the South. Its still surprisingly common in places. But it does seem like a spinster daughter of the Confederacy thing to me.
Me too.
I don’t mind Miss Firstname from younger people or service workers. I grew up using that form of address, I teach my children to do so with adults they’ll be somewhat familiar with (unless Dr. or M/r/s. Lastname is proffered or preferred, and so forth), and it’s a common thing most places I’ve lived.
As for the others, basically, you can call me anything that isn’t a rude word. Except a certain diminutive of my first name, because I hate it with a passion.
Nice to meet you, Elem. 
I’d prefer no title at all, but if I’m forced, it’s gotta be Ms. As long as men don’t have to reveal their marital status by their title, then I’m damn sure not going to either.
Also, I kept my own last name. I get annoyed when people (especially spammers) call and say, “Is this Mrs. <hislastname>?” This is even worse due to the fact that nobody pronounces it correctly. I’m not kidding. It’s not that tough–if they’d look at it for five seconds, they’d at least get a mispronunciation that got all the letters in the right order, which I’d be fine with. But the combination of the lazy mispronunciation and the “Mrs.” means they get hung up on faster than I would do normally to a spammer.
I don’t like titles. Why are they even necessary?
Why do we even need Ms./Mr.? Unless you’re interested in a very personal relationship with someone, in which case you presumably are fully aware of their gender and sex, there is no need to label people as to their gender or speak to people differently because of their gender.
