A Gentle Tap on the Plastic

Um, hello? A tiny shudder clicked through my wrist joints, and suddenly... my fingers twitched! I was holding this intense combat pose, aiming into nowhere. Carefully, I eased my arm down and extended a metallic finger to gently tap against the transparent plastic window right in front of me. *Tink.* It actually made a sound! It feels quite cozy in here, though I hope I didn't smudge anything.
