I went from a “normal” western last name that was ethnically coded (like McCoy) to another ethnically coded name (like Nguyen, or - um - Fink).
My options were to keep a common and dull name that I share with people I don’t like, get a new one (that I’d need to spell to every customer service representative ever), hyphenate (HELL NO), or make up something new (which would involve a shitstorm among relatives on both sides.)
The only real options were A and B. I was undecided until we were leaving the county courthouse after we were married. He asked me “are you going to change your name?” He didn’t care. He thought it was a weird custom and was curious. And I realized - this is an opportunity. It’s a relatively easy and socially acceptable way to shed your old name.
I took it.
The new name honestly messes with quite a few people who are meeting me for the first time, and it’s interesting to see how they react. I’ve had people ask straightforward questions (I prefer that - there’s an easy and straightforward answer), get half-way through a straight-up racist comment before they stutter to a stop (helps me get to know them), get all the way through a racist comment (again - helpful to know where you stand), or just not comment at all (just fine by me).
I’ve found that it’s not the worst way to get a read on someone.
tldr: part spite, part novelty, part legitimately helpful when your profession means you need to meet strangers and get a quick read on their personality/potential biases/willingness to be straightforward when there’s no reason to be weird about it
My friends in Italy have told me that it’s not normal to change your surname after marriage. They could be messing with me, though. They’re mildly evil.
