Chapters
You can't manipulate someone who doesn't give a fuck about being liked. Most manipulation only works because the other person craves validation, like oxygen. If you're cool with silence, cool with being misunderstood, and cool with not being invited, then the tricks lose their power instantly. Why do you think manipulators always target the people pleasers? Because they know all it takes is one disappointed look. One I guess you don't care, and boom. They're bending over like a cheap lawn chair. This shit only works on people who want to stay in the room. If you're willing to walk out, there is no script left.
