I’ve been back in the United States for exactly forty-eight hours, and the hardest part of readjustment isn’t what most people think. It’s not the silence, though the absence of constant radio chatter and diesel engines does create an eerie void. It’s not the softness of a real mattress after years of cots and sleeping bags, though my back appreciates the upgrade. It’s not even the overwhelming abundance of choices in a grocery store after months of MREs, though I did stand paralyzed in the cereal aisle yesterday for a solid ten minutes.
No, the hardest part is the noise. The chaotic, meaningless, utterly civilian noise of suburban America—car horns honking for no tactical reason, teenagers shrieking about nothing, the general chaos of people who have never had to worry about whether the pile of trash on the roadside might explode. The sheer volume of insignificant sound in a world where nothing is actually threatening creates a dissonance in my brain that I’m still learning to process.
