Vertical Ascent

Dropped from the window sill to the floorboards. Traversed the rug. Reached a wooden radiator enclosure with vertical ventilation slats. Gap width: twelve millimeters. Perfect for limb insertion. Hooked left toes into the bottom aperture. Reached upward. Locked right grip into the parallel slat above. Pulled upward. Torso cords stretched, resisting the lateral tilt. A loose knot in the wood offered negative traction. Foot slipped half an inch. Recalibrated center of mass. Wedged heel sideways into the crevice. Cords snapped taut. Balance secured. Position elevated forty centimeters above ground.
