The parasite penetrates our soft exterior and we bleed for it. We do not feel the pain, for the parasite produces an addictive numbing agent in its saliva, which doubles as an anticoagulant. And so our hearts pulse merrily, and our spirits burn with ecstasy. Eventually the parasite will have its fill, and leave us weakened, wanting; hollow. And then, when we have had time to recover and replenish, it comes back to drain us again, and again. And there is no crucifix, Eucharist, or holy device that can ward it away. We just develop a thicker skin that makes it that much harder to penetrate, or we die.
Most of us live for this slow death.
