A tactic I tried in my younger days. Two guys confronted me after one of them has shoulder barged past me. I turned round & both of them started shouting, they wanted a punch up. I stood there and said nothing but just looked at them, I had my arms down but at a slight ready stance. The verbal provocations continued for a long while & asked what was wrong with me.
I still said nothing. They got scared and eventually went on their merry way, They didn’t understand their own situation and couldn’t gauge any outcome because of the complete silence. I call that a win without fighting.
