To my left, a giant glossy sticker watched with round, silent eyes. I held my breath, slowly reached out one trembling hand, and gently tapped the slick edge of the sticker. Smooth. Sturdy. It didn't tip over, did it? I pressed my back securely against the wall, eyes darting left and right, double-checking every corner just to be completely sure.
