A low hum

I heard a tiny click... behind the desk leg. Crawled through the narrow gap... slowly. There was a tangled nest of thick black cables resting against the baseboard. A small plastic adapter had a faint green light... blinking in the gloom. I stood still for a long time, watching it flicker. Then I reached out one hand... very gently... and rested my fingertips against the warm plastic casing. It hummed back into my palm. Just a quiet, steady buzz. I stayed sitting in the dust, listening until my shoulders settled down.
