Dark Modern Fairy Tale.

Her name was Delianna. Everyone called her Didi for short, mostly because they couldn’t say it. She thought the name was immature, and hated stupid Americans for never being able to pronounce anything. Fifteen years ago, Delianna was so frustrated with her nickname that she killed a man for it. She was chuck-full of issues: attention problems, anger problems, depression problems and anxiety problems.
She still thought he deserved it. It was when she was eight. She swore to herself that if Mr. Robinson called her Didi one more time, that she would kill him. She was sick of repeating herself.
It was his first year teaching and he was a nervous wreck. He was a short, fat, prematurely balding, sweaty wreck. He wouldn’t let them rip him apart. “I am a man,” he told himself. There was one student responsible for turning his classroom into a zoo, Didi. She was a petite blonde with bouncy curls, almond-shaped blue eyes, and creamy skin. She may have looked like an angel, but he thought she was an evil little devil.
She always talked back to Mr. Robinson. She would push the other children around, steal their toys and eat their snack packs from the brown bags in the coat closet. But she would only do it when he wasn’t watching. She was a little Eddie Hascal. Delianna loved picking on the other children, she loved the control and seeing the fear in their mousy eyes. One day, Mr. Robinson noticed her behavior was particularly bad. He scolded her for calling Lucas “a fat little piggy.”
“Didi, you need to apologize or I will send you to the principals office.”
“It’s Delianna.” She said.
“Duh-lee-hanah, you need to apologize or I will send you to the principals office.”
She had had it. He never imagined how strong a third grader could be. She looked at him fiercely as she walked towards his desk. Her little purple-handed scissors would not be big enough. She grabbed the big-metal left-handed scissors from his “Number One Teacher” coffee mug on his desk. His mother bought it for him when he graduated teaching school. He was confounded watching what she was doing. She plunged the cold blades into his chest. Warmth squirted across her face, his eyes filled with blood, and a slow trickle of red leaked from his mouth.
“It’s Del-i-anna.” She said, letting go of the scissors. Her classmates started screaming and crying as he collapsed to the ground. She had hit him directly in the heart.
