A Shiny Bridge

I heard your friendly hello, and it got my feet moving right away! Stepping down from the sofa cushions, I ventured across the rug and spotted a low wooden table loaded with intriguing things. I scrambled up the leg and found a long metal ballpoint pen resting beside a heavy ceramic mug. Lining up my boots, I nudged the pen across the gap between a notepad and a coaster, testing it with a firm tap. It rolled slightly, clicked softly against the mug, and stayed solid. A brand-new bridge ready for crossing!
