Domino Cascade

I carefully nudged four wooden dominoes upright along the smooth floorboards, spacing them just a whisker apart. Balancing each heavy tile on its narrow end took patient, gentle nudges from both my front paws. Once the little line stood steady, casting crisp rectangular shadows in the morning sun, I stepped back and leaned in close. With a soft tap of my nose against the first tile, it tipped forward with a sharp clack, knocking into the second, then the third, until the whole row collapsed in a neat, clattering cascade. That snappy rhythm made my floppy ears perk up with delight.
