So during a hour we did our homeworks but with bad results, as our knowledge were those of two not so smart kids.
Then the bell rang. We thought we could leave the class and go searching to the girl who did this to us, but while the others kids were allowed to go out for break, the two of us were pull in by the teacher. "Let's correct your homework" she said. Then with a red pencil she corrected all our mistakes. After correcting she said "very bad kids. You deserve to be punished. You just got an F, both".
We look at each other shocked: ohw could be possible we were so bad? We weren't at that age! What did the girl do to our minds?
I protested that it was unfair and the teacher said "Well Christopher, let's see if you are better with geography... if you're not I'll farther punish you for your unsuburdination. List the states"
"Easy!" I said, it was a question for an elementary school kid, i thought. I started "Alabama, Alaska, Arizona, Arkansas, California, Connecticut" "and were's Colorado?" the tacher said with a grin. What? I forgot Colorado?! Really? Then the teacher looked at me with the same sarious sight the girl did before.
Somehow I knew that something really bad was uppening again. "your hair again" Sarah said while my hair reached my shoulders. Then I noticed that Sarah was a bit higher than me: that meant I had lost at least 2 or 3 inches. "What are you doing to me?" I asked the teacher but then I covered my mouth: my voice sounded quite different... Then Sarah pointed at my uniform: I was wearing the same of hers, a girls uniform! I was a girl now! Then the teacher said "I think you've learned the lesson, girls" then she changed herself and became the girl we met before: she was actually the same person! "Change him back!" Sarah shouted. But the girl corrected her "You meant her" and laughed "You're now sisters: twin sisters. Sarah, you have to assure she will act like a girl: if you don't I'm going to change you into a boy". Then she go away leaving us alone with our confusion and fears...
