In Franz Kafka's "The Metamorphosis," a character appeals to Gregor, urging him to open the door while expressing desperation. Despite this plea, Gregor remains resolute and refuses to comply, reflecting a deeper resistance to interaction and an isolation stemming from his transformation.

Gregor's decision to lock himself in echoes his previous habits from his work life, emphasizing his desire for control and separation. This act symbolizes his struggle with newfound identity and detachment from those around him, illustrating the themes of alienation and the consequences of personal metamorphosis.
