Archetypal Drama

My sister A accuses me of being like our biological father, Tom, the man who abandoned my mother when we were small. My sister A has taken up my mother's bitterness. 55 years later they are both stuck in the same barrel of stinky mud. They both treat me like I am their abandoning ex husband, and it's creepy. I am none of these things but they won't step out of the stinkin' barrel.
