They all really do have the same personality
I grew up with a narcissistic mom and recently moved away from roommates that were a couple that's a narcissist and an enabler
It's kind of how unnerving how easy it was for me to fall back into abuse coping techniques because my roommate was the same person as my mom and I became the scapegoat
He nailed the core tenants of day to day life with my mom
He was annoyed that there's evidence that people use the kitchen (which summarizes a lot of small things) and he would go out of his way to use the water in the kitchen to fuck with my shower
He was also upset that I wasn't just like him and didn't want to be an extra fanboy
One of my more creative coping mechanisms was realizing that they have a quota for yelling at their victim and to give them small things to yell about so they don't go looking for new things and it worked the same for him
Somehow I still can't call it narcissistic abuse to people who haven't experienced it. I just tell people he's got the same personality as my mom because I'll get looked at like I'm the problem and "not all narcissistic people are abusive"
But it sure as heck is a specific type of abuse whether it was when I was a teen living with a narcissistic parent or now that I'm 30 and lived with a narcissistic roommate that's only 2 years older
