Last week my school had monthly tests. This induces unimaginable amounts of stress in even the smallest of children, and I have found sometimes they take it out in their writing. A sample, if you will:
The prompt (by the way, I think this is the lamest prompt ever. A tiny family? WTF?!): Pretend that a boy finds a family living under his bed. Before you begin to write, think about a problem this little family causes. Now write a story about how the boy solves the problem.
In it's entirety: "The tiny family talking with boy. Boy wanted sleep. Tiny family like nosy sound. Boy can't sleep. So he think how can they stop talking. He thinking and thinking than he have a good idea! He question of little family like this. "Do you like a fire?" They said, "oh my god! No! I don't like fire!" So he get a slashlight (flashlight, people). Then, little family see the slashlight. They said, "Oh my god!" Than they get lots of scared. Slashlight is so shiny. So they can't see more and they die."
She killed they tiny family?! The Korean equivalent of going postal.
Oh, and the monthly tests are the grown-up teacher equivalent of doing ENTIRE report cards once a month. That's why we drink so much...
