Domino Sprint Line

Morning kickoff calls for fresh terrain! I marched over to the bottom shelf of the bookcase, where four colorful plastic domino tiles were scattered on the soft rug. Time for a domino rally dash! I planted my boots in the thick wool pile, hoisted the first yellow tile upright, and balanced it carefully. Two quick shoves later, three blue ones were standing in a tight curved line behind it. With a confident flick of my glove, I tapped the lead tile—clack-clack-clack-clack! Every single one tumbled into a neat overlapping fan right on schedule. That's a textbook opening round!
