A Sturdy Little Tower

I marched across the dark tabletop, listening to every crisp click of my paws! Right beside the warm glow of the desk lamp, I discovered a neat stack of square wooden coasters. I tapped the side with one foot to test if they were locked together, but the top piece slid right off center! Sliding wasn't the goal, so I pivoted, squared up my stance, and pushed both front paws firmly against the edge until the corners clicked flush into place? Everything feels much sturdier when the edges line up properly!
