When someone yells at me my first response is restraint. I restrain my immediate response to give myself time to assess the situation.
Surprisingly restraint gives me power in the situation. And often I can see the yeller is distressed but too emotionally weak to contain their own distress, but rather they hysterically seek to put their distress on me, to make me distressed.
Once I realise this my next response is to laugh.
I am laughing at an emotionally weak person acting as though they are strong.
And more interestingly, I can see the yeller is trying to get inside my head and so control me. But by restraining my first response, I keep them out of my head, and so give myself a safe space to act.
