The type of noise that always happens:
it cans be loud in the dead of night,
when thought whirl around and pester.
It can be mundane and unending,
like the ticking of a clock.
It can be impatiently reckless,
causing an anxious, awkward moment.
It can be lethargic
a way to live in peace.
There is and always can be this indescribable, uncharacterised noise.
