Managing the relationship with my unhelpful sister.

My sister is no where to be found. I went no contact with my father, but my stupid family keeps asking me for updates. I told them to call him.
I am not stupid, she is just seeing how things shake out and she will be there with her test tube baby (he is a doll) and her hand out when he passes away.
She has no idea and doesn't care what his living situation is, but then again he doesn't care either. He will bend over backwards for her
I felt bad for making the hospital take him home, but no. Just no.
