If it's over many years - especially in family- it smacks of them not giving a shit about you and that you're unimportant. It's rude.
Yeah this. Anyone who continually spells your name wrong is 9 times out of 10 doing it on purpose. (IMO and IME.)
I used to know a girl at school who was one of 5 kids (2 older sisters and 2 older brothers) but only 8 years between them all. She was fiercely competitive (as all 5 siblings always tried to out-do each other,) and she was always trying to go one better than me.
She got a boyfriend first, she got engaged first, she got a mortgage first, she passed her driving test first, and always ALWAYS 'bragged' that she 'did it first.' I didn't give a shit btw! Then I got a boyfriend and got engaged and married before her. I also had a child before her. When I was pregnant, her 'fiancé' dumped her after 11 years together/9 years engaged.
She was single then, and stayed that way indefinitely. She had been fuming when I got married BEFORE HER - like she actually said 'how the fuck are YOU married before ME?' and 'Can't wait to see YOU with a baby hahahahaha!!!!!'
As the years went on, she constantly spelt my married name wrong, (if it's Jackson, she said Packom, and sent me birthday cards addressed to me with my maiden name on, and sent Christmas cards that didn't include the names of my DC. Several times we bumped into her in town, and she completely ignored my DC. I even tried to introduce her to them and she talked over me. When we left her, my DC said 'mommy why was that lady ignoring us?' I didn't know what to say!
Clearly she had issues, and a stick up her arse because I had a husband and had children, (the thing she had always desired, and had failed to get,) but the disrespect and nastiness from her, ALWAYS spelling my married name wrong, or just using my maiden name, and leaving my children out/ignoring them, showed how bitter and jealous she was, and that she was doing it deliberately.
When we moved house when the DC were late primary age, I never gave her my forwarding address, and blocked her on social media. Never seen her since. Not a great loss.
