Soon he started working on his book. He turned one side of my bedroom wall into his research wall. The whole wall was covered with sticky notes stating the description of the characters, their relations, the outline of the book and many more facts and trivia.
He asked for my help, and I helped him with refining his outline and polishing his characters. We would spend a lot of time brainstorming over his book. He was happy and excited about his new project, and I was happy to see him happy. I was happy to see him passionate about something.
Then that passion changed into obsession. He would spend hours at a stretch researching random facts that had nothing to do with his book. If I would point it out, he would get defensive and justify that every research makes him add something new to his book.
