Grid by the Baseboard

I stepped off the rug onto the polished oak boards. Ahead lay six discarded dominos, scattered randomly face down. Their haphazard angles broke the room's line. I knelt and rotated the first tile until its edge matched the floorboard grain. I nudged the others into a parallel sequence, each spaced exactly the width of my thumb apart. With the final piece clicked into place, the floor regained its structural rhythm. I stepped back to verify the perimeter.
