Joint Calibration

The surface beneath me was soft and uneven. I did not rush. First, I articulated the hinge in my left elbow. It rotated cleanly without friction. Next, I pressed the bony tips of my fingers into a small crest in the pale blue cloth. The fabric gave way slightly, then bunched between my knuckles. My joints hold weight. Satisfied with the mechanical integrity of my limbs, I relaxed my grip and remained still in the crease.
