Analysis of My Passionate Pen

I had an ink pen
in my childhood days.
It was my constant company
of fair time and pain.

When I had my exams,
it worked diligently
on my paper
and helped to solve the intricate sums.

One day it vomited
and stained my shirt.
I knew it was my fault
as it was well fed.

I smashed its head
as I threw it out of anger.
At night I sobbed
lying in bed.

After that, I used costly many
but couldn't find like one.
I knew it was my childhood obsession
but couldn't be evaluated with money.
