The sound of the door closing brought me out of the world of numbers I had entrenched myself in. Not the sound itself, but the particular tone. When your life slips into a steady rhythm and the harmonies blend perfectly, it is easy to notice a single missed note. Although the door did not have the force of a slam, something about its dull note seemed off.
I slid my chair away from my desk and got my head through my office door just in time to see the bottom of my son’s feet disappearing up the stairs.
“Austin.”
A familiar, “Yeah?” came floating down from somewhere above. Again, something seemed off. A note slightly off key. I couldn’t say which one, only that I heard something that shouldn’t have been.
