You get all the puzzle parts together enough to say the puzzle is complete. It's a script. In the process of realizing that, new ideas can come, one way or another. Through a happy accident, they just come to you.
If I even tell anything false, within one minute I have to come clean. And I think most people, even if they're not that direct, it comes out in indirect ways. If somebody cheats on you, they end up telling you they've been spending all this time hanging out with that person. Why? Because nobody can bear a lie. A lie won't stay silent. It makes noise.
