How long had Nene Atang and Nanameka been married?

The story
begins with Nene Atang and Nnaemeka engaged to be married. The first part of the story focuses
on Nnaemeka's father's objections to the marriage, on the basis that his son's fianc©e is from
a different tribe. Nnaemeka hopes that his father (who is named Okeke) will change his mind, but
his father is obstinate and refuses to give his blessing to the marriage.

Later in the story, Nnaemeka receives a letter from his father, which begins, "It
amazes me that you could be so unfeeling as to send me your wedding picture." We are told
that this letter is received "Six months later."

We are then told
that, "For eight years, Okeke would have nothing to do with his son." The story then
concludes with Okeke reading a letter from his son's wife, Nene Atung. In the letter, Nene
implores Okeke to see his grandchildren. Okeke, thinking about the grandchildren he has never
seen, feels "the resolution he has built up over so many years falling in."

By the end of the story, we can thus infer that Nene Atang and Nnaemeka have been
married for approximately eight years.
