So I had a headache. The grandfather of all headaches. You try working on the roof line sometime, with the presses grinding and the overhead cranes wailing and the mechanical arms clacking and grabbing at your inner skull while you snap a shiny sheet of steel like an armored pillowcase and shove it into the maw of a hungry greasy ogre. Noise. Hammering, pounding, shrieking, gobbling, yammering, incessant noise. And I had a headache.
