Crazy how a chance meeting with a psychologist in my 7th decade made me realise that all the sad small minded, mentally unstable, bullies, cheaters, compulsive liars, control freak, narcissistic men and women I actively tried to avoid were actually actively trying to hurt me and the people I loved.

Professional psychologists say it often happens because normal, confident, strong, kind people just cannot understand why or how people can be so horrible, often when the kind, honest, decent people realise it, they become actual victims and it's too late.

It's all very shocking to realise. IMO the best ways to spot the early warning signs, do they lie, do they show signs of jealousy or envy?

Test / watch for this every time you meet new people, I could have avoided tons of bad people if I'd thought about this 50 years ago.
