Myself and my siblings have been invited to a family birthday party. This is the very first family party we have ever been invited to (and they like their parties so there are always lots of them). So what has changed? Well my mum (the sister of the person who's party it is) is now dead and according to the family "it was more trouble than it was worth to invite you while she (mum) was alive".
So Aibu to decline the invitation (and any further contact with the family) on the basis that firstly my mum wouldn't have been such a PITA had she actually been treated like a member of the family and also because I don't deserve to be treated like this by these people?
