Answer:
Based on the Imperialism text from Chinua Achebe's story "Marriage is a Private Affair", the "shared characteristic" between the father and son can be depicted as "stubbornness".
Explanation:
The father and the son wanted things that were separate and different from each other. Why stubbornness? It is because neither the son nor the father was willing to give in and change their mind about the situation. They both stood firmly for what they wanted .
