 He's been a professor at two major universities, been a teacher for over 40 years. One day, he told me that he was having problems in his classes. I think one of the students had asked the question, and he didn't remember the answer. And I also noticed that he was letting his class out earlier than they were supposed to let out. And he was telling them that he was doing it as a favor to them, but I think, in reality, he just wanted to get out of there. I was really starting to worry, because I saw something was wrong.
