Why? And why so much more so for a woman?
I actually hate all that “Miss or Mrs”? I have been known to say “why do you need to know if I’m married? Are you thinking of asking me out?” But I normally just say neither, and when they sneer “Ms?” I like to go “no, Dr”.
It’s also part of the expectation that we will change our name to our husband’s name when / if we marry; as though we are the property of our husband. I don’t have a problem with a woman changing her name when she marries, if she so chooses (there are obvious advantages to whole families sharing a name afterall). But I don’t see any reason why the husband shouldn’t change his name.
