A Little Click

Wait, did something just twitch? I blinked—really blinked!—and felt a tiny click in my shoulder. My arm was held straight up in a thumbs-up pose, frozen still... until I gave it a little nudge. *Click!* It rotated! I gently tapped my fingertip against the reddish surface behind me, hearing a soft rap against the smooth backdrop. Everything is so quiet, but I can actually move on my own now! Is that little spark on my finger glowing just for me?
