You take a pencil and write down. "I wish to be a girl, but I want the change to be graduation, but I also want everyone to remember when I was a boy." The paper than floats of the table, but no one seems to notice.
Paper: Perfect, now that you have made your wish you just need to write your name down to make it final.
You take your pencil and quickly write your name.
Paper: Perfect.
A white light appears from in front of your chest and flys into you.
Paper: Now your change will occur over a week. Have fun.
The paper than vanishes and you go back to a boring day. When you finally get on the bus you see Eileen's not on board, but she did say she would have to get her license soon. You drive home in peace and walk to your room when you arrive. You sit down your school bag and run to the bathroom to see if you've had any changes yet. You take off all your clothes, but still see your normal body. You go with your evening like nothing happened and eventually go to bed.
