Disclaimer: Obviously I'm not J.K. Rowling, so I don't own Harry Potter, I just like to play a bit with the characters.
Losses and gains
I lost my love on a day like this
the trees covered in frost,
and a bitter wind roaming
the countryside.
On a day like this I learned
that love is pain
I gained myself on a day like this
so lonely, I grieved.
The coldness had a
tight hold on my heart.
I learned that true hate
breeds true love
For he taught me
that true passion, true fire
burns within me.
Love and hate, two bipolars
two extremes
in losing him, I learned to love
I really hope you like the poem, and I'd appreciate it if you could give me any constructive criticism.
