Story
In the first day, Rowley Jefferson gets a "best friend" locket which both he and Greg can wear but Greg refuses to claiming its for girls but its actually because that forever word make him nervous (mentioned in The Ugly Truth) and also on the last Saturday, Greg got mad at Rowley for trying his retainer in the bathroom. Then he tells how Greg often gets his facts "wrong" as one day he told Rowley that the boys' and girls' signs on the gymnasium locker rooms were misplaced. Then, Rowley accidentally went in to the girls' locker room, thinking it was the boys' one, making him go to the principal's office. Once, he went to the school in his pajamas because Greg told him it was pajama day. Rowley does things to cheer Greg up because Rowley claims he is "always grouchy." He says that he has to look out for things for Greg and all of this makes them "Best Friends forever."
