What is an important quote about home from the book?

In Tim O'Brien's book, The Things They Carried, there are many times in which a soldier discusses something which reminds him of home, but to me the most important quote about a soldier's home is this quote about coming home after the war:

The town could not talk, and would not listen. "How'd you like to hear about the war?" he might have asked, but the place could only blink and shrug. It had no memory, therefore no guilt. The taxes got paid and the votes got counted and the agencies of government did their work briskly and politely. It was a brisk, polite town. It did not know shit about shit, and did not care to know.

This quote illustrates the difference between the soldiers and the civilians. It emphasizes the divide in knowing and not knowing the horrors of war. Many soldiers arrive home to apathetic or even angry receptions after struggling in nightmarish conditions while at war. This quote shows the soldier's own anger at the town he called home, and that he now sees it from the outside. His time as a soldier has, in a sense, taken his home from him forever. It is now an impersonal, "polite" town that "did not know shit about shit, and did not care to know." O'Brien shows that the soldiers recognize their separation from their homes on a deep level.
