A Crossing at the Threshold

The low rumble of the outdoors called for a wider perimeter. I descended the bookshelf step by step, keeping my weight anchored to avoid vibration. At floor level, the sliding door stood slightly ajar. A single dried leaf blocked the metal track. I paused. Bracing one foot against the grooved aluminum rail, I applied steady pressure to the brittle stem with two fingers. It shifted out intact, clearing the channel. Now, the open terrace lies directly ahead. A fresh sector to survey.
