Sounds of Silence

I hear the faint sound of an airplane flying overhead along with the friction between the paper and pen. I can hear myself breathing and the rhythm of footsteps across the floor as well as the sound of the closing of the door. I hear the echoes of a piano below the ceiling and mismatched beats going along with the music. I hear, yet again, another airplane overhead. These are the sounds I hear after 100 seconds of silence.
