As I read this chapter, I found myself repeatedly wondering if Tim O'Brien had in fact been shot twice. Was that a true part of the story, or was that another made up aspect? The way he made it sound it appeared veritable, but then again that's what I thought about the first half of the book.
Anyway, I must be on a personification roll here because in this chapter anthropomorphism also caught my eye.
"[At night] Tiny sounds get heightened and distorted. The crickets talk in code; the night takes on an electric tingle." (page 195)
Clearly, crickets cannot literally talk in code. I thought it was a good comparison though. At times, when I listen to night life, I get the feeling that crickets are in fact communicating somehow. I'll hear one in the distance, and then soon after hear another one coming from a different direction. Weird, but true.
As for Tim's actions in this chapter, I can't say that I blame him really. Admittedly, he went a little overboard and was slightly crueler than I would have liked, but I can see why he felt resentment towards Jorgenson. After all, he endured lots of pain because of his careless mistakes and had to tolerate being made fun of by the other soldiers. No man likes to have his ego bruised.
