One person stands before you and you use your hand to turn him so he doesn’t see you. It makes sense to do so if a person is acting hostile at times. Do this drill slowly so you find where he is open to the turning and use the lightest touch of your fingertips first and than the hand and only than the fist and arm. Keep breathing and as you progress have him press on you and than come to hit you as you do this simple drill. When you are aware the logical solution will simple be there for you in the way of running from the place or taking him down or simple taking a rock and hitting him in the top of the spine. Do this drill as a person come to you first from the sides and than from the back and only at the end follow the path where you are attacked from the front. The chances are your attacker is not stupid.
