Prompt: Describe an unusual setting as commonplace.

It's hard to stay angry on a day like today, but I seem to be doing alright. The halo of sun through the baleful clouds of dark, granular debris is brilliant and unusually well-defined, and patriotic flags and banners extolling the survival of democracy exalt from their fixtures amidst concrete derelicts that twist their way up through the brooding firmament. A mockingbird with the constitution of a great plains buffalo twitters soulfully from the crooked rise of a parking meter. Even the smell today is bearable, since by now the dogs have eaten most of the human remains, and the remaining humans, in turn, have eaten most of the dogs. On a day like this, I should find my favorite chunk of over-pass and take a nice long nap on the median strip, tilted toward the heavens like a sundial, basking in the rusty orange glow, but even the most earnest efforts of nature's recuperating majesty can't lure me out of the funk I'm in. Not today. Probably not for a while. I guess I just need time to adjust.
I lean against the frame of an upturned tour bus, watching a small family rummage through what's left of a liquor store. Idly fumbling a small ring on a chain around my neck, I think back to the last time I was happy, truly happy, standing on the shore with Thea under the arching aegis of a sky so profoundly blue as to shame my blundering eulogies. The cocoanut scent of tanning oil electrified a subliminal breeze that day, and the sun was everywhere at once; porpoising through the azure waves, flashing from her eyes, finding sea glass in the pillowy sand, and glinting off the simple silver band around her finger. As I closed my eyes for a kiss, pulling her toward me for the last time, I thought my heart would explode, but a large portion of the U.S., China, Pakistan, Russia, India, and the Korean peninsula beat me to it. It was mid-week sometime. I think it was a Thursday.
And that's when this downturn began, this mood swing, exacerbated by the fires, epidemics, and propaganda. It's the most beautiful day since thermo-nuclear apocalypse, and all I can do is mope. I need to learn not to take these things so personally. I need to lighten up and get over it. I mean, it certainly wasn't my fault this happened, and there's nothing to be done about it now. It's just funny sometimes how hard it is to let go of a foul mood.
