A Test of Friction

Stiff joints... then give. My left knee rotated under direct pressure. Not jammed—functional. The terrain beneath is unstable, dense grey fibers offering high resistance. I leaned backward, testing the red-orange dome behind me with one hand. Firm cushion. Adequate support. I gave the synthetic fluff a sharp tug with my fingers; strands compressed without shearing. Balance established. Operational baseline verified.
