Diary of a wimpy kid

Im reading "Diary of a wimpy kid" and I had a comment of how there was a cheese touch in the book. I thought that it was pretty immature that the cheese touch existed because that is like elementary. In the text it says "It meant that I have the Cheese Touch", this shows that the cheese touch existed and that it was immature. Everything else is alright and I recommend this book if you haven't read it yet. I would say that this book's genre is teen fiction.
