I'm not entirely sure either of my parents are textbook narcs but I was told by one of them that they had us (their kids) as a form of entertainment. Which is, like, probably very narcissistic. Self absorbed to the point where he thinks no matter where he is that he is the entertainer and that people are graced to interact with him. But on the flip side is somewhat self loathing in a fake-humble, performative way that is clearly trying to paint him in a specific light.
Also, my other parent finds a way to make everything about her. Tries to make sure she never looks like the bad guy. Spent the entire time my sibling was hospitalized monopolizing the time of the doctors and nurses to turn the entire ordeal into a pity party in which she was the star. Uses my grandmas illness as a social prop and basically feeds on people's (even strangers/acquiantances) sympathy and attention to the point where she'll shoehorn it into an irrelevant conversation. But spins it so she is viewed as sort of a savior/self sacrificing figure and that no-one-suffers-like-she-suffers kind of thing.
But I wouldn't diagnose them as narcs because I don't know if they truly are. They might just be assholes haha
