I tell this about myself because its true and a little weird, but when I was small, my dad taught me how to hook my fingers up and around an eyeball in its socket--just in case I ever had to. I knew what a xyphoid process was at six years old. I knew where to drive the heel of my hand into a human nose. I was taught that I didn't have the physical strength advantage in life, so I had to have the will. I was taught that you have to walk in awareness. I was taught you watch your drink. I was taught to carry improvised weapons. I was taught to see the world in terms of potential improvised weapons.
I was taught this because some boys never get told what they should never try. Or get told but don't really learn it. (You don't use your knee--it's inexact. You grab them by it. You can squeeze and disrupt a generation of losers. And I never had to do any of that. Not once. Because it's really only a small percentage of men who are actual monsters--most are reasonable and not actual sociopaths. I like men, really. They are interesting enough and some have valuable skills. They care for the people around them and often are smarter than they think they are. It's a confidence issue. When you are told to value muscle over brain, you know.)
