I declined because my estranged sister wanted to reconcile. She died a week later of a sudden heart attack.
Did you ever consider reconciling with her?
No, I'm not interested in her.
Communication is the key to a successful relationship. If you're estranged from your sibling, talk to them and tell them exactly what you want from her moving forward.
It's too late for that. I don't care about her and she's dead now so nothing is going to change.
Sorry for my blunder. Yeah, you are right, it's too late now that she's dead. But my advice isn't limited to just your sibling though; it can be for anyone in your life, so hopefully you understand where I am coming from.
