" There is a moment of surface tension when a knife blade presents its demand and the flesh honors it. An instant of pressure before the puncture, the rip before the slide, a small eternity easy to miss but impossible to ignore if you’ve felt it before. I lived in that moment a great while for the small sliver of time it was there. "
