Has Mildred an aim in her life?
Mildred's aim, if it can be called that, is to have a fourth wall TV installed in her home. She is vapid, empty-headed, self-centered and typical of the society. A small part of her probably realizes this which explains her suicide attempt at the start of the story. She is distraught at any change in her life or her routine that inconveniences her. That's why she is upset the day that Montag decides he's too sick to go to work. She spends her days in front of her TV or with her friends who are identical to her. She has no children, no pets, and no job. She runs out of her house, past her husband, mumbling about how everything is gone now, when the firemen pull up in their firetruck, with Montag on board, to their house. It's all about her; she does not show her husband any sorrow for their dead relationship or for what will happen now to him. She has no goal in life other than to satisfy herself and to be entertained.
