The purpose of this book was to make kids laugh. Greg is always doing silly things and getting into trouble.
It is written like a diary. There are not chapters just entries divided up by days. It is written in first person. That means that Greg is telling the story. Greg is the main character. There are a lot of illustrations. There are 1-2 pictures on each page. This is an example of one of the illustrations.
The illustrations are usually funny and show what Greg is talking about in his diary. The pictures are drawn to make it seem like Greg drew them. The font is interesting too. It makes it look like Greg actually wrote it.
