what social expectations does the title character in bartleby violate?

Bartleby is one of the most isolated characters in all of literature. Bartleby's environment cuts him off from nature and often, from other men. By day, Bartleby's window stares at a wall. Wall Street is a bleak and unnatural landscape, and Bartleby also stays there at night, when the bustling human population vanishes and the streets become desolately empty. The narrator makes attempts to learn about Bartleby and help him, but all attempts meet with failure, and the narrator gives up. Bartleby simply has no social life: he remains one of the most isolated characters in literature. Even in wall Street, one is expected to make social connections. Bartleby choses to be alone. For Bartleby, the act of living is the real death.
