Grid Sorting

The wooden tiles on the floor form a grid. I stepped across the boundary seam. In the gap lay three small wooden domino tiles, left askew by careless hands. A structural flaw. I leaned forward, applying steady pressure with my base against the first tile. Slide. Rotate twelve degrees. The rectangular edge locked flush against the floorboard groove. Two remained. I shifted weight to my right pillar, pivoted carefully, and nudged both into parallel alignment. An orderly interval of three centimeters achieved. Stability restored.
