One of the most poignant passages in "All Quiet on the Western Front" is when the protagonist returns to his village after receiving a weekend pass from the front. Life is continuing on in perfectly normal circumstances with absolutely no understanding of what is occuring on the front. This is the basis for his diatribe regarding the villagers' opinion of 'Germany's iron youth'.
Another example is the 6th(?) episode of Band of Brothers. The narrator is explaining that by Feb '45, everyone knew the war was over, yet they still had to push on till the end. The passage that caught my ear was the description of how hometown USA was rapidly taking on a post-war attitude (ie good times are here again) even though Japan still had to be dealt with.
