What DoIDontI said ^
The narcs in my life (one of whom has been diagnosed) also feel the need to remind whoever they're projecting their tirade towards, of how old they are. Just in case people have forgotten that they're adults, given how they behave like children/toddlers during the tirades of abuse.
Because that's what it is.
Abuse.
I also get "you never asked me to [X/Y/Z]!!!" (because they either couldn't be arsed to, or genuinely forgot to) and "you have no friends!!!" (because they don't, at all, and they don't understand that I actually have a very tight-knit friendship group).
Oh!, and the latest?! Telling me that "someone" has done something outrageous, and isn't it disgusting, blah, blah, blah, but this "someone" is all over the Internet, last week - and then last night, the "someone" has mysteriously become someone that they went to school with, sat next to, ate lunch alongside once or twice... how great the disgusting thing suddenly is, because it now has celeb endorsement. When slightly challenged ("I don't want to hear it, you told last week and I'm busy!") they screamed their age and how they "never told [me]!!!" and how I'm obviously crazy for thinking that they did
They don't know the someone, incidentally. The someone might have been at school with them - but they weren't in their social sphere of life, I'm afraid. Essentially? They gaslight, lie, waffle endlessly on about how fabulous they are and how shite we are, and expect us to take their abuse and be grateful for it.
