Early childhood was in South LA. Didn't have a choice. Was good at it.
Last one was as a college frat boy. A brawl that made national news. I grabbed and hurt a guy in a way that scared me.
Since then I avoid physical conflict like the plague. I stay ready to defend, but I avoid until I have no better choice. Also, I'm usually armed these days, so I can't be tussling or fussing with anyone.
