I wrote this quickly in one of my classes, while I was bored.
~~~
Words, terrible words, flashed in my mind at the speed of light. Inside, I wanted to shred everything to pieces, lash out. Kill. I kept composure, however, only letting a few short words snap out. My adversary could only reply just as sharply, her face reddened with what I wished was shame but only knew was undiminished fury. We shared the feeling.
I stormed down the hallway, trying to keep tall and my face unreadable, but was only half successful. I thought of going back, confronting the human vermin, but my cowardice prevailed. Within minutes, I found myself in class, sitting, wallowing in self-pity.
For years, I’d hated her very soul, dreamt of stripping her very heart bit by bit. Imagined the day when she’d disappear. But it never happened. She was always there, the female incarnate of Satan himself.
No matter how much I told my mother how detestable this girl was, the only response I’d receive in return was, “Girls will be girls. Nothing you can do about it, my darling Keira.” My mother didn’t understand me—girls had changed in their ways over the years. I loathed this girl, unconditionally hated every part of her. I was set on the fact that she wanted to turn me against my friend. Actually, I was certain of it.
She named me awful things behind my back. Spoke slander, lies and creative tales. I would never stoop to her level. I would never give her reason to tell those awful things.
And the reason why I hated her so much was that I didn’t know why she hated me.
I really liked the fact that this piece was short, to the point, and fulfilling. In that short text you managed to give us a character with emotions, someone people could relate to. So, good job there.
