There’s one in every family.
I had an aunt like that. She was my mom’s youngest sister who was always certain she was being slighted and not given enough attention.
The whole family suffered because of her antics. Decades of discord passed, before SHE did.
She was proof of the saying: ‘People who are easily and readily offended are displaying a profound and pathological sense of inadequacy.’
It’s the Meghan Markle syndrome.
I attribute it to ENVY.
