In Second Class Citizen by Buchi Emecheta, Adah, the protagonist, experiences the harsh realities of being an immigrant in Britain. She finds that the white society is largely individualistic, and there is a lack of warmth and communal support compared to the close-knit community she was used to in Nigeria. This shows that the members of the community are unfriendly towards immigrants.

In Buchi Emecheta's Second Class Citizen, Adah’s experience with the white society reflects a lack of neighbourliness and a sense of isolation. Several key moments in the novel support this view:

1. Adah's Isolation in the Neighborhood:
   When Adah and her family first move to England, they are faced with a society that is indifferent and often hostile to them. Their neighbours show little interest in befriending them. Adah notes the lack of warmth or communal bonds in the area. This is reflected in her initial struggles to connect with those around her. The coldness of her neighbours leaves her feeling isolated, even though she is physically surrounded by people.

2. Racial Prejudice and Segregation:
   Throughout the novel, Adah experiences racism and prejudice, which further underscores the lack of neighbourliness. Her efforts to engage with the white society are often met with rejection or indifference. This is reflected in the difficulty she had while searching for a new apartment in London as everywhere she went, the sign that read "Sorry, No Coloureds" was posted. It is also reflected in the fact that Trudy was able to get away with the negligence of the children placed under her care, even when there was glaring evidence that she was a bad caretaker.

These examples illustrate that Adah’s view of white society in Second Class Citizen is one in which neighbourliness is indeed lacking, as racial prejudice and indifference create barriers to connection and communal feeling.
