The Undergorund Man (be it Open Pit or Shaft) "The Underground Man’s alienation manifests itself in all kinds of relationships.
When walking in the park, he obsesses about whether to yield the right of way to a soldier whom he does not even know. Then, in a confused attempt at social interaction, the Underground Man deliberately follows some school acquaintances to a dinner where he is not wanted, alternately insulting them openly and craving their attention and friendship. Later that same evening, the Underground Man attempts to rescue an attractive young prostitute named Liza by delivering impassioned, sentimental speeches about the terrible fate that awaits her if she continues to sell her body.
When Liza comes to visit the Underground Man in his shoddy apartment several days later, he reacts with shame and anger when he realizes she has reason to pity or look down upon him. The Underground Man continues to insult Liza throughout the visit. Hurt and confused, she leaves him alone in his apartment.
Here the Underground Man decides to end his notes. In a footnote at the end of the novel, Dostoevsky reveals that the Underground Man fails to make even this simple decision to stop writing, as Dostoevsky says that the manuscript of the notes goes on for many pages beyond the point at which he has chosen to cut it off."
