Within these chapters one may find some repetition with the atmosphere, and temperature, although, it does involve unique character developments. For instance, Miranda's Mother, who has sprained her ankle for the second time, has begun to grow weaker, eating less, and is not communicating as much. Although some uprisings occur within her character when a true feast is brought to her, which then encourages her to change her ways, even if only for that time period.
A theme means to be the universal idea of something, a moral lesson, and although each chapter in Life as We Knew It has it's own theme, there is always a theme that can encompass all subjects. A recurring theme of which I have found while reading through this novel is that, although there might be an event that causes such catastrophe, even if only a fragment, humanity will still prevail in points that are difficult. For example, on November 30 in Life as We Knew It, Miranda has an inner thought causing her to find a gift for her older brother, Matt. Soon after Mrs. Nesbitt's death, she finds a coloring set so once "[Matt] stop[s] chopping firewood...he can take up art again, to go along with his philosophy studies."
However, in doing something normal, or humane, during this event can be challenging for the characters. An example of this would be with Miranda's Mother, who is gravely affected by the prices at which gas and oil have been set, or by the decreasing food supplies. This then leads to her being mainly anti-social, and being in poor condition, showing how worried she actually is, and that her facade is easy to see through. This also causes her to be in an ill mental condition, which comes early on, like in the beginning of the novel, she refuses to give to the poor, even if only a little amount of supplies. Although, this can be interpreted as protecting her family from the harsh conditions to come.
Yet, her mother is not the only one to be affected in such ways, Miranda herself also goes through similar stages. At many points in the novel, she is anti-social, or whenever she is social, she isn't in the best of moods, and takes it out on her mother. The apocalyptic events also have caused specified gender roles or stereotypes of those genders. For instance, when collecting supplies from Mrs. Nesbitt's house, Miranda and her mother stay inside, while Jonny and Matt carry in the rest of it. Or how Matt and Jonny are the only ones doing manual work like chopping down trees for lumber. For a conclusive ending to this exercise, the characters are not in the best situation, but as Miranda and her family continuously say, they're better off than others.
