I sometimes wonder if a lot of its ragebait and fake too, but when Pearnisa goes off on someones looks i know its genuine and shes seething.
I base this on that Pearnisa truly believes she is beautiful.
Its so obvious by her language and actions over the years.
When she attacks someones looks she believes its the ultimate surefire felt, because she, a bombshell woman that everyone desires just called out someone lower on the ugly tree. It's over.
And i believe she is actually so mentally ill that her brain just doesn't see anything that challenges this, which is why she goes dead quiet when all she gets back is ridicule and why she just does it over and over again.
