Personally, I would not be interested in a woman who felt like she needed to keep her last name. I think that displays too much type-A behavior and there is only room for one type A in a relationship(I being the other type A). But I would support a couple who chose to go with the woman's last name.
So, in short; You = more important than her.
Which is sort of the point I've been trying to make all the way through this thread.
But I absolutely LOATH people who hyphenate their names because they can't figure out what to do. Because of their lack of ability to communicate effectively before marriage and make a decision they make the GENERAL PUBLIC suffer by having us pronounce extremely long last names.
Yeah, I loath people who treat both parties in a relationship as equals. How f-ing outrageous. And yeah, it's so difficult to pronounce words longer than 7 letters, I don't understand how this could ever work.
It is not only inefficient, but also pretentious. What makes you feel like you are so important that people need to garbble out MULTIPLE last names to greet you formally. And then the children being at school, having to explain why mommy and daddy have different names- the whole thing is a mess.
Maybe in 1940 they did. Nowadays, nobody gives a *&^%. Nobody even gives a *&^% if you're a kid and you have two daddies.
At least not in the part of the country that believes in evolution. Not sure about your local area.
