That. The number of American colleagues who assumed I'd just change my name was mind blowing... Not like they were assuming my husband might change his!
And then the reactions when I told them it wasn't legal to change names upon marriage here.... Oooooh boy.
Huh. It's hard for me to imagine this really being an issue.
When my wife and I got married, I figured that she would change her name . . . I guess because it's the traditional thing. She told me that she didn't want to change her name because it would be a big hassle . . . all her bank accounts, bill payment stuff, her work stuff is set up with her current name. So I was like "Yeah, makes sense." and that was the end of it. One of my Grandmothers regularly addresses Christmas cards to us to Mr. and Mrs. GuitarStv . . . but other than that I don't think anyone's ever made a comment about it.
Actually, thinking about it . . . of all my married friends I think that only one woman changed her name to match her husband, so maybe separate last names is the new normal? Keeping your name or taking someone else's name isn't really making any sort of statement to me.
Here's how it went for us (x100 conversations), for those who didn't already assume I was changing:
To me: "Are you changing your name?"
Me: "No"
To him: "And how do you feel about that?"
I found that pretty offensive - that there's implication I need my husband's blessing to keep my own frickin' name, but he's not even asked whether he's changing his name. If the follow-up had been a query on my reasons why I wouldn't have found it nearly so upsetting. If I hadn't wanted to keep my name in the first place, I think those conversations would have persuaded into changing it.
Couldn't get my grandmother to get my name right so I gave up on it. Now it's address to Mrs. <his first name> <his last name> which while irritating, I concede is technically correct form of address (that I wished never existed as it subsumes my identity).
In my circle of friends with professional degrees & careers before marriage, publications in names, etc., (excluding those who are particularly religious) it's less common to change last names than it is in my high school circle of friends, who got married just after college and generally didn't get additional degrees.
