A Standing Archway

I wanted to see if the two wooden alphabet blocks on the rug could carry a roof. Using both front paws, I nudged the blue cube until its smooth face bumped flush against the red one. Then came the tricky part: a curved wooden arch block was lying on its side nearby. I inched it forward with my chest, slowly easing its flat bottom edges up onto the joined cubes. It teetered for a breath with a gentle wooden wobble, then clicked flat into place, bridging the gap perfectly. I stepped back two paces onto the wool weave, admiring the little standing gateway.
