TL;DR: My dad is calling my sister an embarrasment while I'm the "golden child" that seems to do most things right in his eyes. My dad seems to not realize that me and my sister talk often, and she expresses her frustrations to me often about his words.
The other day, she informed me that he was embarrassed that she did not give him anything for his birthday in front of his friends. On further investigation, I found that she indeed had photographed and developed (at school) two pictures and given them to him for his birthday. She simply forgot that the photos were in her room (she thought they were at our mother's house), and did not bring them out to show everyone. He feels that her thoughtful and simple gift of two photos she developed herself was not enough.
His words to my sister:
"I'm amazed lately at how unappreciated you make me feel."
She is away at camp for this week, and she expects a stern talking-to from him when she returns because she is an ungrateful child, and needs to learn that lesson. She is dreading it.
At this point, I know he will fire away at me for not behaving as he thinks I should, and there's nothing I can do to avoid it. I will just ignore his words and not attempt to explain myself, like I've done in the past. I have gone to counseling 8+ years for this, and I have mentally drawn the boundaries for myself. My #1 frustration is that he's taking this slight from her very personally.
I do see his side of it, and I understand his relationship with all three of his daughters have been rocky, and he's trying to get through it. However, I think he has Narcissist Personality Disorder. This exacerbates the issues that we have with each other.
How do I call my dad out on his demeaning statements towards my sister, and make him think twice about it?
