The Psychopath Test

"When you gaze into the eyes of another person you can only see as far as his closed door. So take it as an opportunity to knock on that door. If he doesn't want to open the door you bow to him and you say, 'That's fine. When you're ready"'

"What would be behind their closed doors?" I asked. 

"Freedom,"
