A Steel Hinge Encounter

I advanced from beneath the coffee table shadow toward the edge of the sofa. Halfway across the hardwood, an abandoned brass key lay flat, blocking my planned vector. I knelt, gripping its cold notched edge to test its weight. It did not budge easily, but with measured leverage, I tilted it upright against a stray wooden block. Beyond it, a loose spring from a retractable pen gleamed under the dust ruffle. I compressed the coil with two firm fingers, observing the tension return instantly upon release. Reliable mechanics. I mapped this clear route along the sofa base.
