Words, Tone, Body Language.

"Choice speech is a non-aggressive dialogue to buy time, to determine how much trouble you’re in — is [your assailant] a talker or a fighter? It helps you shift psychological gears, create rapport and use words of an emphatic essence. Rather than say, 'Don’t do that!' you can say, 'How would you feel if someone were doing that to you?' It creates an introspection in your attacker which buys time and what we call 'orientation moment' where you ask yourself, Am I getting closer to violence or further from violence?”
