It was remarked upon how many attendees hadn't been 'in their lives' in any real sense, for years. But appearances were important. So they turned up.
Probably like rural Ireland, tbh.
That's not correct -- unless you're a local politician pressing the flesh or something. The idea that you only attend a funeral if you're a close personal friend/relative of the deceased simply doesn't apply in Ireland.
As a pp said, people who may never have met the dead person show up to support the family. If I died now, all my parents' friends, and people from the various things they volunteer with, and former colleagues of theirs, would all attend, as well as a large extended family from both sides, neighbours, and DH's enormous extended family and that's not even including my friends, colleagues, ex-colleagues, DH's huge circle of friends and connections, all of our mutual friends and neighbours, and DS's school friends his entire class would probably be given leave to come, and some of their parents. And that would be perfectly usual.
If my parents have been on holiday, I or one of my siblings have often gone to the funeral of someone they knew to represent them.
