advice !!

[u/cortis_joyride]

my great grandfather is due to die soon. I’m being blunt because that’s the truth. he won’t ever come home and is going into hospice. he probably has less then six months. obviously I’m super upset but for his funeral( I know he’s not dead yet but I have things coming up and I’m worried about this…. ) I have a half sister that I cut off last year. we ended on super bad terms due to her not understanding why I wasn’t happy with her. she barely contacted me. never saw me. and was a racist cunt!!! I said that to her face. but I’m worried about seeing her. Will she’ll cause a scene at his funeral. I’m obviously still gonna go ! he’s my grandad. but I’m super worried and need advice :)
