My brother is 32, still lives with mother, says she's a cerebral narcissist, blames her for everything. But still doesn't work, won't find a job. She cooks, washes the laundry. He won't even put the dishes into the dishwasher. But when he even senses that she's gonna ask him what his plans are, there's a 2-3 day barrage of insults and a laundry list of wrongs done do to him. So far, only zyprexa is preventing him from doing something stupid.
