Civil War

It was crazy and in love
It loved to cause pain and it was exiled to the uterine cell
In a prison called the female body
And spent days thinking about the escape plan and causing pain
It involved soldiers called Hormone
And that was the reason for success on some days
It was starting a Civil War
With severe pain and instability and bleeding
And it enjoys watching painful internal battle
The only reason was madness
Madness for a creature called Period.
