This is a page for Greg Heffley's relationships and interactions with the other characters throughout the series.Greg and Rodrick is complicated and perhaps the most important one. They tend to fight and argue with each other. In Rodrick Rules, Greg had a very embarrassing secret, which was of him accidentally going into the ladies bathroom of Leisure Towers. Rodrick throughout the book kept on threatening Greg that he will spill it out if he provokes him or tells on him. Rodrick seemed to know that Greg had a crush on Holly Hills in The Last Straw because when they were in a hotel room, Rodrick lied to Greg by saying the Hills family is staying in a room next to theirs. Greg fell for it and Rodrick pushed him out of the door and locked it. Greg was also in his underwear making it even worse for him. Although they tend to fight a lot and will not show their feelings openly, they truly love each other more than anything else. Rodrick and Greg are rarely seen getting together, however at the end of Rodrick Rules, Greg and Rodrick bond and end up getting along with each other. Although he did not show it, Greg worries about his brother many times and doesn't want to see him sad. Their close bond is further shown in the films, in Dog Days when Rodrick found a Spag Union DVD in the mail, he immediately showed it to Greg claiming they are both in trouble though mostly Greg, Rodrick expressed strong concern for Greg being shipped by their father to Spag Union and advised him to do his best in Wilderness Explorers to make Frank change his mind. Greg also tried to help Rodrick in getting Heather's affections by helping Löded Diper in being hired for Heather's Sweet Sixteen, which lead Rodrick to happily hugged his brother in gratitude though Greg was annoyed when Rodrick ignored Greg's advice of being dressed in tuxes and to play Heather's favourite music in excitement.They are also on somewhat good terms in The Long Haul film. Greg. He is childish and Greg often takes advantage of him. It was later revealed that when Rowley moved into the neighborhood, he knocked at Greg's door and when Greg opened it, without even introducing himself, he started saying jokes from a book his mother bought him. Greg felt for Rowley and forced himself onto him. Greg has shared his opinions on Rowley's parents, claiming they are overprotective of him. Greg treats Rowley as sort of a slave, making him do work and give him piggy rides. Greg thinks that he will boss over Rowley and tell him what to do. In the movie Greg doesn't seem to do things like that to Rowley, treating him more than just friends, but still keeps giving his advises to Rowley. Rowley and Greg's relationship is quite strained as they keep fighting and breaking up, then after a while they reconcile their friendship such as when he dumped Greg as a friend for his girlfriend Abigail. Greg, despite thinking of himself as a good friend of Rowley, he actually kind of bullies him and also uses him. Greg truly cares for Rowley as a friend and is strongly protective of him as shown in the first film when Greg covered up Rowley by claiming to be the one who ate the cheese, when his schoolmates almost found out. In the Film: Rodrick Rules, when Rowley stole the limelight in Rodrick's party, Greg tell his brother he can beat him up in place of Rowley showing selfless care for his friend.
Greg completely despised his younger brother, Manny, because his parents always treat him like a prince and would give him everything he wants and when Greg and Rodrick were his age, their parents were more strict with them but mostly due to Manny constantly spoiled or break Greg's belongings such as inserting a cookie into his video game player and got away unpunished due to his parents's pampered protection. His parents excessively spoil him too as they are never seen scolding him even once. In Cabin Fever, he switched off all the electricity except the one for his room throughout the electric panel. While his family was struggling, he was enjoying himself until Greg found out that he did it as he wasn't taught how to tie his shoelaces. He always tells lies and gets away with it like when Greg was playing with Manny in New Year's Eve and found a little piece of thread, he told Manny it was a spider and started pretending if he was making him eat it. Just then Manny slapped Greg's hands and the thread went inside Manny's mouth and he swallowed it and told his mother. He got away by showing his mother it was the size of an orange and Greg was sent to bed early. He also has imaginary friends that get him out of trouble and make him get extra dessert after dinner. His friend is Mikey as of Hard Luck. This makes Greg feel bad since he doesn't have any friends. Greg's hatred of Manny is extreme to the point that he will exploit any chances to get back at Manny for revenge, by calling Manny Ploopy the same abusive insult Manny invented during Church in Easter, resulting Manny breaking down crying and Greg leaved the church with a gloated smile on his face.
Susan dearly loves her second son although Greg actually does not get along with Susan as she often embarrass Greg by calling him affectionate words like "Sweetie", "Sweetie Pie" and "Honey Bunches". Susan always takes Manny aside and she would not tell Manny that his imaginary friends are fake otherwise she thinks he will be traumatized. Greg hates how his Mom never punishes Manny and treats him like a prince and spoils him, even though he changed his password on Net Kritterz, changed the parental control and refused to give the password, and cut power in every room except his in Cabin Fever.
Frank thinks that video-games are just a thing to keep Greg away from exercising and he would make Greg eat more and work-out.

In Dog Days it is stated that they don't have much in common with the exception of hate for the comic Lil' Cutie.
According to Greg, his uncle Charlie brings everything he asked for him on Christmas. However when he asked for a Barbie Dream House when he was younger (thinking it would be a great fort for his toy soldiers), Charlie went and bought the first thing which had Barbie in it, this caused Greg to get a Barbie doll, and when Greg asked him from Twisted Wizard, he got a photo of himself about the same size as the box of Twisted Wizard. When Greg was little, he used to call him "Red" which was because Greg had red pajamas, however Greg took it seriously. He told his mother about it, and she bought him blue ones, but Charlie gave him the nickname "Blue".
Arthur/Clyde is the great-uncle of Greg and only says "Muurp" and "Ruup" instead of words, making Greg confused if he is actually meaning something or not, so Greg just takes a response that would be suitable like "No thank you".
Greg finds Fregley weird and creepy. Whenever Greg is going to Rowley's house, he always sees Fregley in his backyard, saying creepy things, this causes Greg to go through by going in the gutters. When Rowley broke up with Greg and was hanging out with Collin Lee (his backup friend), Greg thought of making him jealous by having a sleepover at Fregley's. When he went there, he would stay away from Fregley as far as possible. Fregley then apologized to him for chasing him with a booger. In the film, Fregley chases him with a booger instead.

In Dog Days. Greg had a crush on Heather Hills. He thought that if he would get good with Heather he could get a high school girlfriend (a thing he has been wanting for a long time) and so he could show off to kids at his school. So then he found that she is a lifeguard at the pool. When they got to the pool Greg would go to the pool which she is lifeguarding on and Greg would exercise in the bathroom so he could have his muscles pop up. Greg thought to impress her he would say anything to a kid doing anything bad (which Heather was supposed to say). Once a kid was feeling bad and he vomited, Heather went to clean it and asked Greg to help her clean it, but Greg just ignored her because he was scared of cleaning the vomit. Soon Greg thought that Heather will soon go to college and that long-time relationships won't work. In the Dog Days movie, Greg doesn't has a crush on her, but in the credits he appears trying to show his muscles to her and her friend.
