Thoughts on today's reading

While I was reading there was a part of the book that had to do with another familiar book. At one point he brings up the cheese touch from The Diary Of A Wimpy Kid, there's nothing really special about it but the thought about it is cool. I've never read a book that has a reference to another book, especially one like this. Something else I read about had to do with him dealing with his problems and how he tries to get along with people.
