Diary of a wimpy kid

Here is a frustrated quote:

"Rowley is technically my best friend, but that's definitely subject to change." Greg (p 17)

This quote sets up Greg's and Rowley's friendship, which we'll see develop, collapse, and then be rekindled over the course of the book. We know from the get-go that Greg feels conflicted about his relationship with Rowley, and doesn't really feel all that committed to him as a friend. This will become relevant later.
