Ongoing #61/Harrow Daily Poem #17

Another day, another doodle. This one is part of a machine made up of cogs and levers.
Here's the rather short poem to go with it.

The Metaphor Machine

Pull the lever, press the button,
Turn the dial and flip the switch.
The machine begins to work;
It all goes without a hitch.
No one seems to notice
That it doesn't do a thing
The machine we know as life
Has got a broken spring.
