Trumwill has a post in which he discusses societal norms with respect to the conduct of weddings. The particular norm he examines -- that a father walks his daughter down the aisle to "give her away" -- wasn't one I had been required to think about during my own wedding. The future Mrs. Φ was very attached to the symbolism of this tradition, and as you might expect, I had no objections.
But one of the commenters brought up an issue that had rather more resonance: the last name. I have a vague sense that a fair percentage of women, even ones with no socio-political axe to grind, go through some "separation anxiety" with respect to their maiden names, and Mrs. Φ fell into this percentage. At some point, she made noises about keeping her maiden name, and this became one of the issues we discussed.
Supposedly, there are some cultures that are matrilineal, by which I mean women keep their last names and pass them to their children. (I don't have any specific examples of this, but I am assured that it is so.) Hypothetically, were I the product of such a culture, I would not have any objection to following its rules. I can't think of any theoretical reason why matrilinealism is superior to patrilinealism, or vice-versa.
But . . . in our culture, a man with a wife that keeps her maiden name is saying something very specific. He is aligning himself with . . . those people. And I had no desire to align myself with those people. I had no occasion to keep company with those people, nor did I aspire to. And it didn't matter to me that Mrs. Φ wasn't trying to make any kind of social statement about "equality" or anything. So this was, potentially, a deal-breaker.
Ultimately, the compromise, such as it was, was that she would keep her maiden name "for work". Ultimately, the work never materialized, Mrs. Φ got on the mommy track, and I'm pretty sure we haven't discussed the matter in nine years.
