Explanation:

Richard Wright's "Black Boy" is an autobiographical account of his early life in the Jim Crow South from 1912 - 1927. And the passage in the question is of when Richard's mother had taken him to his father's place to ask for money. But his father, Nathaniel Wright doesn't seem to take them seriously, nor his responsibilities as the head of the family. Instead, he is openly living with another woman and deserted his family. The passage is intended to show his dismissive treatment of his own son and in general, his family and their needs.
