"When we were in primary school, Margaret Glenn stole my homework, put her name on it, and then put my name on her blank homework, which caused the teacher to punish me by making me stand for the whole class. Later..."
Mrs. Herd curiously asked, "What happened later?"
Scarlett Glenn sneered: "Later, I applied a layer of wax on a tight corridor by her desk. When she walked past it, she slipped and knocked out two of her front teeth."
Mrs. Herd gasped, "Ah..."
"Do you think I'm a bit cruel?"
Mrs. Herd shook her head: "No, you're very smart."
She could think of this method even in primary school. At that time, Mrs. Herd spent every day trying to figure out how to eat snacks without being seen by the teacher during class.
Scarlett Glenn laughed, "Look how adorable you are. Later on, I did more things to take advantage of Margaret Glenn. Now, I've managed to get her into a mental hospital. Do you think I'm a bad person?"
Mrs. Herd nodded blankly: "Bad... but you're very good."
