My Grandfather was a massive prick to my grandmother (who died a few years ago) and my father. He recently died of pancreatic cancer, hooked up to an oxygen tank and had a bag of stuff attached to his side.
The whole time I was praying that the old guy would say sorry, or just apologize for being such a massive cunt throughout his life and blowing off me and my sister and calling us 'not real grand children'. But he didn't, so he died a single man with two sons who want nothing to do with him and a few grand children who know nothing about him.
I did get $250 in the will.
