fox I completely agree. Quite frankly unless you have been around the deceased within the past year of their life why bother at the funeral - too late surely? I've been shamed into attending funerals of people I hadn't met. I had nothing at all to contribute and don't know how my presence was supposed to have helped anyone. I'm not doing it anymore unless I feel that I will mourn the person's death, how can I if I've never met them?
Exactly!

Am I reading your post right??? The parents of your deceased cousin (who you've had nothing to do with since childhood,) have never forgiven' your sibling who couldn't attend the cousin's funeral? A cousin that neither you (or your sibling) had had anything to do with, for several decades? 
Good grief. With people like that, you're better off with them not in your life. Your sibling is better off with the cousin's parents 'never forgiving' them IMO.
You say your cousin's wife didn't even know who you were, so she also would not have known your sibling either. So I cannot understand the big deal that they didn't go to the funeral.
I think it was perfectly acceptable for your sibling to not go, given the circumstances, (like the fact you'd all had nothing to do with each other for several decades.) If you wanted to go, that's up to you, but I know for a fact that I would not be going to the funeral of a person, if we had had nothing to do with each for several decades - even it was someone I was related to.
If they had meant that much to me, I would have maintained contact with them over the years. Anyone who I have lost contact with (or has lost contact with me,) means nothing to me. Therefore, I would not attend their funeral. And I certainly would not want them at mine, with their faux mourning, and 'competitive grief.'

Unless the cultural background states otherwise, I think not turning up at a funeral only says : " I don't give a shit, I can't be bothered".
Oh yeah I agree, if it's someone you know, someone who has been in your life constantly for many years, and someone you care about.
Going to the funeral of someone you have not been in contact with for several decades, is somewhat attention-seeking, and quite honestly insulting. You couldn't be arsed with them when they were alive, (for MANY years,) so why are you showing your face now?
I can only surmise that people who do this are either a) feeling guilty and bad for not being arsed for so many years. OR b) there to see if there's anything for them in the will. OR c) there to be nosey, to make out they care, and to get a free buffet and free drinks.
As I said, they were never around when the deceased person was alive, so what are they trying to prove by turning up for their funeral several decades last being in contact?!
