Answer:
It shows the clash between traditional village and modern city life.
Step-by-step explanation:
In Chinua Achebe's Marriage Is A Private Affair deal with the dilemma of a couple who decided to get married despite being from different tribes. And as is customary in the native village, marriage is arranged by the parents and love plays no role in it.
As seen in the given discourse between Nene and her would-be husband Nnaemeka, it is evident that the young man is anxious about informing his father about his choice of a wife. Even when Nene wants the father to be included in their "happy news", the young man simply stated that it is impossible to know if it'll be good news to him. And when asked further why it shouldn't be good news, Nnaemeka mentions that people in his village "are most unhappy if the engagement is not arranged by them. In our case it’s worse—you are not even an Ibo." Moreover, Nene being from Lagos "knows very little about people in remote parts of the country", which is a reference to his native village.
This discourse is a reflection of how the traditional village and modern city life clash against each other in their traditions and approaches of life.
