I found this book disturbing.
That's right, if you have a scab touch it. What does it feel like? Hard, bumpy. Like scales on a lizard. Like the hard earth in a parched land. Like the skin of a t00-oft tanner. Like a heart locked away.
Smell it. What does it smell like? Nothing. Existential non-ness. Like a piece of dead skin. Death itself. Good like that. Like a mystical walnut.
Go ahead, eat it. What does it taste like? Like an over-cooked filet. Like beef jerky left out in the rain. Like a neglected kimono. Delicious perhaps. Strangely, even provocatively so. You shouldn't like it but you do.
This what is good about scabs - you can grow them yourself, as much as you want. To touch. To smell. To eat. Scabs.
