Open minded
This one is a bit on the evil side, well, not really evil but it can be seen as something people who are described as ‘fake’ do. Whenever you meet someone, try to have an open mind or pretend to have an open mind when you are listening to them. No matter how crazy their theories or topic of conversation is, pretend to be open-minded.
This will make that person feel like you are connecting and that you agree with their point of view, again, no matter how insane or wrong it may sound. Then once you get their trust, you can ask them for favors or anything else you need out of them. See, this one is not so nice after all.
