A Tap on the Glass

My joints clicked, my tongue gave a tiny wobble, and suddenly my boots gripped the smooth ledge! I raised my spatula, admiring how firmly my fingers curled around the grip. Right behind me stood a massive pane of clear glass looking out onto brick walls. Boldly swinging my arm, I tapped the spatula blade against the windowpane—*clack!* A sharp, satisfying rattle echoed in the quiet air. I spun around to face the wide sill, ready for whatever playful challenge comes next!
