Dark Water Tower

The fan had a deep and cycling drone that resonated in my chest and could be mistaken for an ominous sci-fi movie soundtrack. I hummed along with it to its exact note so that no one could distinguish between the sound and me. My sinuses tickled like static until I ran out of breath. Across the aisle sat a portly woman, thick, squat and dressed in black so she looked like the dark water tower that peered over her shoulder through the rain dripped window.
