For Bender, we can clearly see that he doesn't seem to take anything seriously, and his behavior also shows that he doesn't want to make any commitments. For example, Bender has had many girlfriends before, but it seems that he has not committed to each of them and is constantly looking for another one. In reference to Brian, we can see that he simply takes on the role his parents assigned him to be a nerd. He doesn't even question what his parents asked him to do, but he just accepts it. Based on the opening scene, we can see that John Bender's parents didn't send him to the library at all. He demonstrates that his parents do not care or care about him and displays characteristics of neglectful parenting. Furthermore, it is very likely that Brian Johnson has authoritarian parents. It's because his mom asks him to find a way to study even when he was in detention and not let him express his opinion out loud.
