When you are talking to someone, suddenly look behind him. He will immediately turn and look behind himself to see what it was that made you look. If you do this 3–4 times he will be throughly creeped out and will actually change his position so he can himself command the view of what’s behind him. It works even better in a situation where there’s a view behind. This trick is truly creepy because in the right kind of ambiance, the person feels there’s someone he cannot see, and quickly freaks out.
When you are talking to someone, look at your watch with sudden movement. The person you are talking to will feel very uncomfortable that he is encroaching on your time and will try to leave you. He may even ask you if yo are in a hurry. (Somehow, looking for time on your mobile phone does not produce the same result, though looking at a wall clock does.)
When you are talking to someone, abruptly shush him in the middle and try to act as if you’re trying to listen to something faint that he couldn’t hear. You might add some special effects like: ‘Hey, did you hear that?’ Very creepy! Do it a couple of times and he will turn very uncomfortable.
When you are talking to someone, if you lower your volume or whisper, the person will automatically lower his own volume to suit your pitch or whisper back, even if he doesn’t know why you suddenly whispered. It works best in argument situations, explanations, lecture or controlling others when somebody is getting louder than you like. You lower your volume and he has to climb down.
