It doesn't bother me too much. My father passed away a few years ago. I do get a bit sad but he had a good long life and we were never real close. I wouldn't let your sister have the last word, if you feel like talking with your dad call him. But if you are going to get emotionally abused it wouldn't really be worth it, would it? My thought is life is short so if you have something to say to him you should do it. Better than having regrets later on. I am sorry you are hurting. Sending good vibes and gentle hugs your way!
