First Tap

Everything was still. Then, a tiny ripple stirred through my lower edge. I tilted forward just a fraction. My left funnel dipped downward, its rim tapping the clean, flat floor beneath me. Clink! A crisp, hollow sound echoed up through the opening. Oh. That sound came from me. I leaned down and tapped the surface once more, listening closely as a soft, bright vibration hummed through the quiet space.
