1.Awareness is king. Because I heard/saw the guy as he came around the corner, I was not caught completely flat-footed when my world went abruptly pear-shaped.
2.Action > reaction > passivity. My wife asked me later “why did you throw your coffee at him?” My only reply, and which remains my reply is “seemed like the thing to do at the time” – but from a 10,000 foot view, tossing my coffee had major impact on the encounter which was to switch the initiative from my would be attacker to me. By throwing my coffee, I was forcing him to react to my actions instead the other way around, which gave me the opportunity to retrieve a better weapon than a cup of coffee.
“carry your f***ing guns, people!”
a .25 in my pocket beat hell out of the 9mm I left sitting on my desk at home.
All very good points
