[...] Ironically, a good part of his anticorporeal stance (it was his idea to call having a body Corporeal Punishment) derives from his non_fatal flaw, the skin trouble, the skin trouble itself deriving from a weekend years past, just before a cattle call for a Wisk spot he didn't get, a weekend of solo camping and getting-into-collar-soiled-character, with a tent, in the Berkshires, West of Boston, during which he'd contracted a mild spatter of poison sumac, and had purchased a discount generic brand of poison-sumac medicine he curses now and forever (like most terse-labeled generics the product was untrustworthy, turned out in fact to be medicine for the _sumac, not the sufferer therefrom, but if the label says MEDICINE FOR POISON SUMAC what the fuck are you going to think, standing there?) that had set his face, neck, chest and back aflame: pulsing, cystic, volcanic, allergic, clotted, almost sacredly scarred. The sumac is so bad it hurts--which of course is a constant reminder that it's there, on his body--and it won't go away, no sooner healed by brand-name antitoxin than reinfected. The whole thing's just pretty loathsome, and you can bet Sternberg loathes it. He's unhappy, but in that comparatively neat and easy way of those who are at least pretty sure they know why they're unhappy, and what to curse, now and forever.
typical long-winded DFW passage but also hilarious (honestly the characterisation of Sternberg is amazing)
