O’Brien starts by saying, listen to my story, I swear it’s true then the first thing he says is basically, never believe a war story, none of them are true. The first of many contradictions.
The psychological repercussions of PTSD turned writing style that make themselves most apparent in this particular story are not only the many if not dozens of obvious contradictions, but something more that comes across as literary mood swings.
My first example is that he starts his story about a characters' letter to a dead comrades sister, he begins by raving about the guy and then ends the portion of the story in an anticlimactic, "the old cooze never wrote back”. Another example is when describes the two mens interactions leading up to ones death, he re-iterates the innocence and lightness even goofiness of their interactions almost desperately and then boom, the guy gets blown up.
There is a pattern of things being peaceful and nice going negative and scary. He says you’re brother’s a good guy and we had amazing times, to I miss him like crazy and you’re a cooz. Also, these two guys are best friends and really silly, then one dies. And then during Mitchells story when twilight was beautiful, the river was peaceful, then the shadows and mountains become mysterious and unknown. He almost seems hysterical and desperate as the author.
Hysteria comes back in his description of Rat’s encounter with the baby buffalo. His writing, to me, becomes unnecessarily violent and over the top. I think he goes on and on about this one messed up detail, the intensity of which, could have been done in a single sentence. again, the writing seems hysterical, almost unstable.
The question of how does Tim Obrien’s writing reflect PTSD is difficult because it’s a semi autobiographical piece so it’s difficult to separate what is just the story from what could actually be part of his personality. He even says so himself in the story, fiction and reality are blurred lines. Tim O’brien is an incredibly intellectual guy but that's hard for me to connect to because this story seemed hysterically written, but maybe that was his whole point.
