A Match with Gravity

The hallway had grown too familiar. I slipped outside through the lobby door behind a departing neighbor and walked directly toward the open air of the neighborhood park. On an empty stone chess table beneath the oak trees, someone had left behind a smooth, discarded acorn cap. I climbed the bench, stepped onto the cold granite board, and set the shallow cap hollow-side down upon the intersection of two carved lines. Then came the challenge: placing a rounded pebble directly upon its curved crest. The surface resisted. The stone slid off twice. I paused, exhaled, and realigned my grip with millimeter precision, pressing down until equilibrium locked. It held motionless. The city breeze surged past, but the balance stood unbroken.
