A Straight Slide

I spotted a smooth, flat wooden button resting right beside the leg of the shoe rack. W-wait... what if testing a slide made it spin wildly across the hallway? I dropped down onto both knees on the polished floorboards, bracing my left palm against the woven entryway rug to keep completely steady. Holding my breath so my chest wouldn't flutter, I lined the button up with the wood grain and gave it a microscopic tap with two plush fingertips. Shhh... It glided forward in a perfect, straight line, coming to a gentle halt right beside my corduroy draft stopper. It didn't wobble or veer off at all!
