From a few steps away point your finger toward your partner (and former friend’s ) eye and start moving slowly toward him with the intent of making contact with the eye ( keep the speed low). Your partner needs to:
1. Keep breathing
2. move toward you instead of away from you
3. Keep his ability to cry in stereo by moving in such a way that you do not make contact with his eye
Repeat the drill changing roles each time and see how you react to this real threat of discomfort and possible harm if you range yourself out of self governance.
Advance to the same drill only now you start the movement not as a response to your partner but choosing to start moving from either shoulder to spread your awareness instead of letting someone dictate where you focus. Again advance to starting the movement from either hip to spread your awareness further in the body.
The more you pay attention, the more it pays.
