One place in the setting that i think is significant is the green zone. It is a part of Iraq where Matt was deployed in the army. It's significant because it's a safe haven for war victims to just relax. This is very significant because the Iraqi's never get a chance to rest from terrorists, because of the constant war that is going on between them. The fact that they can go to a place without fear running their lives, is a benefit no matter what you may think. I could imagine myself where I know that there is someone always watching over me. I mean even on tests I get worried so I can't really imagine how worried they'll be when someone is threatening their life everyday. It's significant for Matt because it's kind of a place of rebirth for him. HE has to re-learn everything again, such as walking and talking. It's just a safe haven for all. It's alsoa good place for Matt to get out of the war zone.
Another significant place in the story would definitely have to be the hospital itself, the more specific place that I mean is the bed where Matt sleeps and basically where the ICU he's in. I think it's important because Matt gets to learn about himself again. Not many people get to learn about themselves because not all have been in concussions. He learns about himself, because of the time it takes for him to say what he wants, so he gets to think about what he's about to do before he actually does it. It's a place of re-invention that makes it so important to the content of the story. It's a rebirth and it actually helps him forget about the actual terrors of Iraq. Hopefully when he re-invents himself it will last after he leaves the hospital.
In conclusion, Matt gets to learn about himself in the setting of the ICU, and people have a safe place from the terror of the war in the green zone. These two make a great setting, that really represents something in the story not just a place that comes and goes.
