Whenever my narcissistic father said or did something that shocked and angered me when I was growing up, and, of course, not being allowed to actually say anything, I just looked at him in dismay, he'd say:
"Why are you looking at me as if I'd killed your father?"
What a bizarre thing to say, right? I knew what this was supposed to mean: "I, your father, am the most valuable thing in your life, and killing me would be the most heinous thing anyone could ever do to you, so whatever I might have done to you is tiny in comparison and you'd better remember how precious I am to you right now."
But it has an eery double meaning. In a way, he did "kill" my father when he made sure I'll never know who my real father is. I wonder if he realized that when he said it.
