Not just for metric calibration anymore
Larry Horn, following up on "Hyperbolic scalar indifference" (7/14/2015) and "Expletive deficits" (7/18/2015), points to the following passage from Augusten Burrough's 2003 memoir Dry:
Background: Augusten, 90 days sober after a stay in PRIDE, a gay rehab facility in Duluth, followed by group and one-on-one sessions and AA meetings back in Manhattan, has fallen for Foster, a guy from group who's incredibly hot but also problematic—off-limits not only because you’re not allowed to get involved with someone else from group but because he’s just relapsed and is smoking crack again. Augusten and his British recovering-crack-addict-temporary-roommate Hayden are discussing the perils of Foster over an Indian dinner.
"At least I can understand your attraction to him, after seeing him”, Hayden says, breaking off a piece of papadum.
“He is possibly the most attractive man I have ever seen in my life. He’s quite literally breathtaking. I no longer blame you at all for your shallowness and lack of judgment.” […]
“I don’t know, my obsession with Foster is kind of fading. It’s like he’s severed my give-a-shit nerve. I’m over him.” [Emphasis added]
Larry adds: "Unclear where this particular nerve is located."
