After what felt like 20 minutes of wrestling and blows, my arms were slick with sweat. I was exhausted. It felt as if my arms were hanging from their sockets by thin strings. But I had more to lose, and I’d always been a stubborn fighter. I eventually managed to throw the guard to the ground and climbed on top of him, sitting on his heaving chest. I pinned both his hands with my left hand and started punching him in the face as he turned it this way and that, trying to evade my blows. I felt no rage anymore, no emotion at all. I was like a miner gouging out a seam of coal. There was no hatred left in me, only determination. Bang. I gashed his lower lip on his teeth. Again. I took a deep breath, leaned forward, and gritted my teeth. Bang. Harder. Bang.
