In the beginning Tim O’Brien tells how he wrote to his friends sister informing her about her brother's death, and including a few stories of his bravery. Then he goes straight to the point and says ‘’A true war story is never moral. It does not instruct, nor encourage virtue, nor suggest models of proper human behavior.’’ it's like telling a experience, not many people will listen to the story but if it is edited then it will catch people's attention. You can sometimes tell if a story is true or not.
Tim O’Brien in his writing speaks through his words, beyond them, like when he told the story of the men on watch for 7 days.
