Op the sheer lack of consideration for you mum/his gran in particular really shocks and angers me.
He's doing NOTHING to remotely make her feel welcome let alone an important and wanted guest - which he should be.
Again, if any of either of my grans grandchildren had behaved like this their parents would have ripped their heads off in order to put them back on straight!
His priorities are fucked up! Somebody needs to tell him so.
Have you or db2 spoken with dns father about all this? About HIS failure as a father to deal with this?
IF any of my cousins behaved like this and their parent didn't put them straight (I can think of one situation where it came close) then the parents siblings would have taken THEM to task for their poor parenting.
"He lives with his mother. He’s probably known this woman all his life. For all you know she’s the mother’s best friend." Still absolutely NOT a good enough reason to prioritise a fucking neighbour over family!
Somebody needs to tell this ARSE wipe (clearly it needs to be in words of one syllable) to get his head out his arse and treat his family better and learn some bloody manners! I think the time for polite eggshell tiptoeing has passed.
I think the time has come to ask bluntly WHY you weren't deemed good enough for a full invitation.
Enough's enough the air needs clearing, especially since it seems there's likely to be confusion for other guests with who will be there - his own brother had no idea you weren't properly invited. That suggests to me he DOESN'T have a remotely legitimate reason for not inviting his aunt, uncle and cousins (not that I thought there ever was).
I highly suspect there's going to be a snobbery issue behind all this and it may well be down to bride as well as groom.
Do NOT mistake quiet for benign.
"Yes mum has asked but DN just said that there wasn't room for everyone" which you know is bullshit from the numbers involved. Someone - it should be his father but clearly he's a gutless waste of space - needs to get the TRUTH out of him.
"We don't know whether the bride's aunts and uncles are invited or not." Time to ask! And do it face to face too.
This is such bollocks! Someone needs to have a serious word with this little twat!
