The repetitive motion

So small
A toe in a shoe
Up and down
A beat of 120
In its own metronome

The bouncing of a leg
The calming movement
The concept of being ok
But is it
When it bounces like a bunny?

Then the hands
Knuckles knocking
So fast so long
Surprising the bones haven't chipped away like stone being carved

Simple
And completely uncontrollable
"Just stop shaking"
I would if I could
But like an out of control coaster
I just have to ride it out
Until the body crashes from exhaustion
