I am a paternity tester and have been in the industry for ten years. I have handled more than 10,000 paternity test commissions and "dismantled" more than 2,000 families. Working in such a job, I am used to seeing all kinds of weird people and weird things, the dark psychology that people try to hide in normal times, and the shocking things people do when they are disappointed or even desperate... I use my eyes and my pen to write down these people and things, and truly present these explosions of human nature in desperate situations. I hope it can cause some people to think or learn from them.
