My mum is a psycopath. A life time of abuse and truly screwing the system through selling drugs, her body which was for pleasure and personal gain because she was robbing people of thousands, organized crime and murder via the Ulster Volunteer Force, losing two children she never cared about both through adoption, killing her father by overdose because he was blind and never knew any better for money she would inherit, because her brother’s wife’s older brother won the lottery and dished the family out with some money to live comfortably, but not her for what she is… the worst of it all was, I never knew any better.
She used me to get a free house because in this country the government pretty much gives you a house if you have ‘mental health problems’ and I was put down as her carer, you also get one for having children, so more power to get one. I know now why I awoke (from sleeping on the floor at her house one bedroom apartment) to her taking pictures of me 
so she could apply for a move.
Anyway, they are truly the most hurtful, calculating, manipulative people imaginable, and think they are god’s gift to the world. A tell-tale sign I noticed from spending time with her is long-winded stories about, humour and very few, if any, reciprocation about you in conversation. Oh and lots of mimicking of your kindness and affirmations.
The good thing about these people is they are like robots with the affliction of human error trying to assimilate into society. They will screw up eventually because there will always be someone bettee, and karma is a killer. It’s good to know that in the end even psychopaths know fear :c)
