On the Saturday after the first week of school in Diary of a Wimpy Kid, Greg says that, "Rowley is technically my best friend, but that is subject to change." Greg and Rowley have an interesting friendship, and Greg can be very mean to Rowley at times. At the end of the story, however, Greg doesn't tell anyone about Rowley eating the cheese and takes the fall for the cheese touch.
meaning is simply a character who undergoes some important change in the course of the story.
he does not want people to know he is best friends with rowley and is mean to him but takes the fall or blame for the cheese touch and tells no one it was actually rowley
