DW and I have been married for 9 years today - (both female, which I think is relevant to the story). My DW took my surname as I didn’t want to change my name and it was important to DW that we share a surname as we planned to have children. I would have been happy with both of us keeping our names but the decision was made.
It was my DWs birthday yesterday and a late present arrived today from FIL addressed to wife using her maiden name. DW late GM also did the same before she died. I just laughed but DW is annoyed. Her family don’t do this to her DSis who has been married for 10 years to a man. I do understand why she’s annnoyed though, but we will just ignore it and move on. I don’t know if it will bother me more though if he continues this for our baby when it is born, as the baby will only have my surname.
I guess my question is this is rude right or are we overthinking it?
