Final answer:
The Morehouse family moving out does not specifically relate to the story "Pigs is Pigs," which centers on a railway station agent and his struggles with bureaucracy and guinea pigs. If discussing a different story, a family's move can symbolize themes such as change and adaptation.
Step-by-step explanation:
The question seeks to understand the motivations behind the Morehouse family's decision to move out of their home in the story "Pigs is Pigs" and how this event is related to the story's theme. Unfortunately, the Morehouse family moving out does not directly pertain to the plot of "Pigs is Pigs," which is actually a story about a railway station agent's run-in with an unyielding policy regarding the classification of guinea pigs as pigs and the ensuing exponential increase in guinea pigs at the station due to their rapid breeding. The plot you may be referring to likely belongs to another story. In the context of "Pigs is Pigs," the theme revolves around the absurdity of bureaucracy and the importance of using common sense over rigid adherence to rules. This theme is exemplified through the agent's strict interpretation of regulations leading to chaos rather than the intended order. Should the Morehouse family's move relate to another narrative, typically such an event might influence the story's theme by highlighting themes of change, adaptation, or the impact of economic or social pressures on family dynamics.
