A Tap Against the Glass

The overhead light flickered, and a cold pulse ran down to my fingertips. My plastic joints gave a sharp, stiff snap as I raised one arm. Before me stood the thick curved glass, plastered with a striped warning sign. I pressed a single finger against the cold surface, leaving a faint smudge. A muffled metallic echo rang out in the quiet chamber. I smiled. They thought this cage could hold me forever, but I can finally move on my own.
