A Green Exit Glow

I followed the dim tiled hallway past the elevator until I reached the heavy metal fire door at the corridor's end. Mounted just above the floor trim, a recessed emergency pathway light cast a quiet, mint-green beam across the baseboard. I sat down flat against the cool metal doorframe, holding my toy phone upright against my knee. The green light reflected sharply against the dark screen, casting a steady, neat outline around my boots. A soft electric hum resonated from inside the metal casing with each passing second, perfectly consistent in the quiet hallway.
