And sometimes
It's a shame
When you don't
Understand
The heart
Of understanding
When the pistons
Fire
But they miss
When they 
Bump and grind
But they're
Left 
To their own
Tune
And though
It's all about timing
Sometimes
It's about
Misfiring
And however much
Oil and dirt
However many
Mechanics 
You throw 
At the problem
This machine
Is different
And to caress 
And touch
Doesn't always
Make it
Better
