A Gentle Hum

I followed a rhythmic trembling in the floorboards toward the quiet corner behind the sofa. Sitting there was a large, matte-black wooden box emitting a steady, warm rumble. I watched it for a long while before creeping close enough to press my curved forearm against its side. The steady vibration traveled straight through my body, soothing and deep. I rested my forehead against the dark grille, tilting my head to match its gentle pulse.
