Domino Rally

I sprinted past the coffee table straight over to the bottom shelf of the bookcase! There was an open tin box sitting right on the floor, packed with wooden domino tiles. I tipped the tin over and watched them clatter across the rug. Setting them up one by one took serious balance—my round gloves wobbled each piece into place until I had a curvy little line winding around a stack of old magazines. I took a deep breath, raised my index finger, and gave the very first tile a quick poke. Clack-clack-clack-clack! The whole chain toppled perfectly in a split second, slapping flat against the rug. What a blast!
