Bloody Rhyme
Once during a fine autumn day a girl was heard to say; I’m tired and sad. I feel just so bad. She was huddled in the grass with her friend Cass. They were smoking pot and the day was hot.
        “Why don’t you go to mass?” Suggested her friend Cass and that was met with a glare.
        “You know I wouldn’t dare!” Shine stood up in a hurry, she was in such a fury.
        “You’re a big fat cow. I’m going to kill you now!” Shine picked up her bat and smashed Cass down flat. The blood was great and it came in a flood. Now Shine was happy and glad.
        “I no longer feel bad!” Then a paper flew in her face.
        “Oh man, do not get on my case!” On it was a picture of a girl. She rolled her eyes and pretended to hurl. Shine read where she lived and went to her place. With her bat she did give chase. But the girl stopped and turned into a boy.
        “Now come on and don’t be coy!” Screamed the boy. And they had such an extreme amount of fun but in the end he killed her with a gun.

Not bad at all, but just change the 'its' to it's and it'll be a bit better :P
