Kevin needed to be smart about this. He thought about all the things he could do, but he was fearful that things might go awry. He needed to talk to someone about the notebook. He thought about his classmates. Clearly the smartest kid in school was that Japanese exchange student Raito Yagami. Surely, Raito could help him put this book to Kevin's best use, but just to make sure Kevin picked up the notebook.
"Raito Yagami will come over to my house to advise me what I should avoid writing in this notebook. He will be totally without self interest in the advice that he gives me, and when he leaves he will forget everything that we discussed."
Kevin had just finished writing when the door bell rang.
Kevin closed the notebook and headed to the door. He opened it and stared into a strangely bewildered Raito Yagami's face.
"Uh, you go to the Albert Einstein High School too don't you?" Raito asked, "I was studying at the library up the street and suddenly I had a compulsion to come to your house. Why do you think that was?"
"Because I wrote that you would in a very special notebook that I found," Kevin said as he explained what he had done.
Raito listened in awe, and then answered, "Well, if I had a notebook like you describe I would use it to make the world a better place."
