100% agree with * GrammyGrammy*. Funerals became invitation-only during lockdown and it’s time to let that go. A friend left comments cards on seats at her father’s funeral and said she had never heard many of the stories about her father written on those cards, she was so pleased. Many people must have enriched your father’s life, and vice versa, who had nothing to do with you, it would be kind to welcome them. The niece is right- it’s not the slap up meal that’s important, it’s the shared memories of your father. Also it might be that they have health issues, as they are not young, so DS has offered to accompany them. In this case they probably need a friendly face with them as well.
That said, I am really sorry for the loss of your father.
This is not a funeral.
I understood that the scattering of ashes is normally a rather private and highly personal event usually attended by close family members on invitation.
If the host is paying for a meal afterwards, surely those invited should not take it upon themselves to extend further invitations to others without at least asking the host - not as this niece did, by telling her that she would also be bringing along her son?
And the comment about the sandwiches was just plain rude. That is not the way you talk to someone who you've never met but who has included you in the invitations.
Jannabell has decided on this celebration for her late father, and it's not up to anyone else to tell her how she should have gone about it. She probably knows better than anyone else that the "posh" meal is not the most important point, but that's the form she's decided it will take, and she has every right to do so, and doesn't need others pointing this out to her.
