I didn't change my name when I got married 32 years ago, so it felt slightly silly to change it now. But I'm old enough to vote, drive, get a tattoo. Hell, I'm old enough to join AARP. I think I'm old enough to decide what my name is.
Once I reached 30, I was convinced I would never take another's name. I'd had this name too long, and after this many years, I've learned to love it. I know who I am with this name; I don't know a new-named version of myself.
