Adrienne, I see both sides. I'm sure your sister has a ton of unresolved issues where your mother was concerned all on account of your dad's bad behaviour. On the other hand, I very much see your side and the pain your sister caused your mom by her absence. I could never know what I would do in your situation because mine is far different. I'm glad I was at my dad's funeral even though we were mainly estranged except for right before he died.
