There's this big roll-up door in the warehouse factory I work in that's not often used. Today it was open for ventilation. When I walked past, I could see bright blue sky. Cool spring air, with a touch of chill just enough to counter act the warmth of sun on skin. At the edge of the unused parking lot, a chain-link fence, then open grass field bordering the woods.
I had to turn back, back to the heat and the grease and the black dust of the factory. Back to work.
