Caffeine -
A demon.
Observe its mode -
It takes a victim,
Makes it ill and tired,
And robs it of sanity.
It holds the heart and kills the head.
The victim-prisoner is awake
During the darkness, the reign of terror.
Poor little person.
Poor little fool.
That's why you don't drink coffee
And never add sugar to tea -
You couldn't handle it.
See what you've done?
Why did you do it?
Well, do me one favor, if you please -
Turn the lights out as you go.
