Winston's memory of his mother and his sister serves to give the reader more insight into Winston's past and thus more insight into his character as an adult, into his motivations and why he does the things he does. He remembers a time when a gesture, such as embracing a child, could be done merely for the sake of itself, without catering to a political purpose. This memory reminds him of the proles, who do things just to do them, unlike Party members, who do things only because of their duty to Big Brother. Winston feels that the proles are the only hope for society to regain its humanity.
Winston's thoughts about the proles lead to one of the most important conversations between Winston and Julia. They discuss what they will do when caught. Although they know that they will confess to every detail, they are both sure that their actual feelings cannot be altered, that Big Brother can never get to the inner workings of the heart. They agree that the Party will make them inform on each other, but it will not be able to make them stop loving each other. This conversation is one of the greatest ironies in the novel and foreshadows what ultimately occurs between Winston and O'Brien and Winston and Julia.
