People keep asking (and by people, I mean my mother, over and over again) how we decided that Marc would take my last name. It was pretty easy. I wanted to keep my last name, because I like it (it's very rare- pretty much all the people in the US with it are related to me). Marc wanted us to have a family name and didn't feel particularly tied to his last name. And New York state is one of the few where a man can change his name through a marriage license as easily as a woman. So that was that.
I haven't heard too many negative opinions of this decision (although I'm not sure the word is totally out yet). My grandfather was pretty confused, but I'll give anyone over 80 a pass. And what I find particularly funny is that anyone who meets us in the future will see our matching last names and assume that I took Marc's last name. A revolutionary in disguise!
