Alwayshave, in the thread above me you write: "If you decide to duke it out when you could have left, your going down for battery."
This I completely understand. If I were physically attacked first I'd yell at the top of my voice "NO!" squarely in his face (this tends to surprise and intimidate) and then I'd step on his foot and knee him in the groin. Then I'd kick off my heels and run away as fast as I could.
