NH told me about some moves like that. Raising the arms seemed to me opposite of what he's saying, leaving my sides or abdomen open for injury. Instead, it is seen as a ready to strike move, eh? But it is all intuitive, isn't it? You're seen as someone who is able to defend themselves when you posture yourself like that, is that what the guy in the video is saying? The possible attackers intuitively know you know the moves. Eye contact sends a message too.
Caribou, were you and the young guy staring each other down standing still, or walking towards each other? I was confused about the part where you said, "...I saw a young man that put me into condition orange. I moved over to the side of the aisle away from him. As soon as he turned toward me I walked between two parked cars so the only way at me was straight ahead. We stared at each other for three or four minutes and then he turned and left. I can't prove that he was going to attack me. I do count it as a win because I never had to fight."
Yes, a win.
