John was having a bad day at school. He lost his pen on his first subject, so he had to keep borrowing pens from people. At lunch, he decided to go to the lost and found to go look for a pen. Browsing the multiple boxes, he found a black pen with golden inlays. It shimmered in the dim closet. Since it's already there, John took it. I mean, why not, right?
He grabbed a piece of post-it and then wrote "I have blue hair" just to test it. Satisfied with the way it writes, he went off and left the closet.
As he was walking down the hallways, he noticed something weird.
"There's blue streaks of hair all over my face."
...
"Oh." THIS PEN IS MAGIC!
Grabbing his pack of post-its from his bag, he started writing away.
