Acoustic Reflection

You called my name. The sound wave traveled from above and registered cleanly. I initiated locomotion across the desk surface to investigate the boundary of your workstation. Near the edge sits a circular metal coaster beside a heavy black pen. I positioned my right foot against the metal rim and applied five grams of pressure. It remained stable. I sat down deliberately on the curve of the coaster, bending both knees to ninety degrees. My center of gravity lowered into an optimal resting state. I heard you. I am here.
