So the assignment was to write a story that you are swimming in the ocean at night with a shark. Our teacher said that the shark could be friendly if we wanted to write that way, but, knowing my twisted personality, I did not. :P
So here is what I wrote:

I don't know why this happened. Why? Why did it have to happen to me, when I was alone, none the less. "No! No, not me!" I was bleeding. Something was missing. My arm? My leg? I couldn't tell, but I did know I had to keep swimming.
"No! Let me live! Please, god, please!" I could feel the creature just gnawing at me. I couldn't escape.
Now I came to my senses. I could tell what I was missing. My left leg was gone, no...not just gone, but devoured. "HELP!" I screamed, no one was around. "Anyone! Please, just save me!" It was pointless. It was midnight and pitch black, without even the moon to illuminate my suffering. "Not me! Not now! I-"
My meaningless pleading was cut short as I was pulled under. I kept struggling and struggling, but any amount of effort was futile. I came to the sad truth of things after that. I was going to die.
The next morning, my body was found. Eaten and, almost, unidentifiable.

So that would be the end... Please note that this was written in around 15 minutes.. :/
And after that, to much of my dismay, my teacher read it in front of the class.
I was not happy. >:c
So anyone who is reading this, please comment and tell me what I could do to improve. :D
It would be greatly appreciated.
