My mom has NPD. And she had designated me as the reject in the family, way back when I was around 8-9 years old.
Imagine having your mom saying she regretted that you were born. After she called you all sorts of names. Or even (trying) cast you out of the house (my dad managed to calm her down). All that when you were just 9 years old, only because you didn't answer her call. (I was listening to music; normal stuff)
Mmm, she's the origin of my AvPD, alright
My dad on the other hand, was an introvert, so I didn't get any deeper in analysis, but aside that, I think he was pretty normal.
