My cousin was in hospital dying of cancer. I spoke to my mum and she said she wasn't sure what to say etc, so she ended up not going. I went. I said to him "hey this situation really sucks". We had a great conversation. He died. I'm really glad I went.
Fast forward a few years and my uncle (his dad) was in hospital dying of cancer. I spoke to my mum and she said she wasn't sure what to say etc. I said "you remember what happened last time. Just go." She went[1]. It was a good way to bring finality and say goodbye to her brother and she was really glad she went.
[1] I also went separately but that's slightly beside the point
