A Sheltered Channel
Your quiet nod gave me courage to glide further across the wooden floor. Pushing slowly with both flippers, I found a dim, tranquil cavern beneath the low coffee table. The air here was cool and sheltered. Nearby rested a stray paper bookmark, lying like a flat drift of seaweed. I gently nudged it with my snout, watching it slide an inch across the polished floorboards before settling in the dark.
