Perhaps this ought to be in AIBU but I’m not interested in the usual MN bunfights, I actually want to understand the thought process involved.
I gave a lunch party for a family member’s birthday. The thank you letters have rolled in - not expected as family guests only, but obviously I was delighted to receive them. As usual, my mother-in-law and my sister-in-law have used the married surname I have never used on the envelopes. I’ve been married since 2005, so it’s not news. I’ve told them, politely and on numerous occasions, that I didn’t change my surname on marriage. They still insist on using it.
The usual MN explanation about this behaviour tends to be of the insecure cunt/ generational misunderstanding/ jealousy about professional qualifications or career kind. I’m as certain as I can be that these don’t apply to my MIL or SIL so I’m asking now: if you deliberately change the surname of a married woman, why do you do it? Is it an etiquette thing, or a contempt thing? What are your thought processes? Because choosing to use a different surname to the one a person has been known by for nigh on five decades clearly requires some thought, no?
