Final answer:
Moira's reasons for getting mad at David are not stated. In literature, characters become angry due to a range of emotional issues, from jealousy to miscommunication. Their anger is revealed through their interactions with others and the situations they encounter.
Step-by-step explanation:
The reasons for Moira getting mad at David are not explicitly detailed in the content provided. Various characters in literature exhibit anger for different reasons, often due to underlying emotional conflicts, miscommunication, or disagreements.
For instance, Jane Withersteen shows anger because of perceived dishonesty and jealousy, a human emotion that can drive characters like her into rage. Similarly, characters in other contexts may react with anger when dealing with loss, disappointment, or even when faced with their own vulnerabilities, as shown by Dexter's uneasiness during dinner with a character slipping into moody depression.
Characters in literature are complex and their anger, like Moira's, can stem from a multitude of factors that are revealed through their dialogue and actions as they navigate their respective narratives and relationships with other characters.
