I'm not a narcissist, but I definitely have gotten enough explosive narcissistic shrapnel from my father. I'm sort of wired that way, but I don't feel that I'm pathological, so all I can pull from is my own existence and my knowledge.
When I was young I thought: when I am 60 my necessities will be very different. As I get near that age, I realise they are similar to what they were when I was 25.
