Ds was 4 in Aug, he had a party and ds and I sat down and decided which of his friends he wanted to invite. We sent invites, friends came and a good time had by all. Both sets of grandparents came too.
But as it was just a 2 hour childs birthday party it didn't even occur to me to invite any of my sisters as a) one was on holiday and B) it was a weekday afternoon and 1 was definitly working and I assumed the other one would be too.
I have 3 sisters, and 2 of them came to see ds on/just before his birthday with presents and cards for him. Neither expected to be invited, and if I had then couldn't have come anyway.
But my third sister, who noone ever sees, and who I haven't seen since Christmas (her choice, she stays well away from the rest of us, hasn't seen my mum or dad since fathers day etc) has now taken offence.
It wasn't a conscious decision not to invite her, I didn't even think about it. It was only at another family childs birthday that it became clear my sister was annoyed at me (she wasn't there btw, as it was for children only)
Anyway, i have now recieived an email with just this on it
'My invite got lost in the post then'
and nothing else!!!
I was a bit at first, but actually I'm quite upset now. At no point as she ever invited me/ds to anything and we sometimes get a card or sometimes not on birthdays, and when I got married last year, we asked her to be involved, and her dh to be an usher and they refused. So tbh I have kind of put her out of my mind.
So AIBU to have not invited her? Is she being U now?
And how should I respond back to her..if at all?
