'Learn the rules and break them' was written on his T-shirt when we played tennis together for the first time. Should I have noticed it? Much, much earlier? Yes, I should have. But by then, it was already far too late. Psychopaths weave a sticky web of lies, slander, and intrigue. Once you're caught in it, it's almost impossible to escape. You flail around, but it's completely futile. 4% of the general population are psychopaths. Not all of them become murderers. I wish for close cooperation between courts and psychiatrists. I wish there were free points of contact for those affected within courts, public prosecutors, and the police. Clever psychopaths - and that's most of them - often go unnoticed for a long time. For far too long. If you come across one, turn around and run as fast as you can. That's the only way. Believe me. I know what I'm talking about.
