What is the comparison made between American/Western Cultures with African cuture using the vocabulary? Nzolo, Nzolani, Nzole and Ngana?
What screams at me most loudly when reading your question is the fact that in the language of the Congo, the same word can mean many different things depending on the tone of voice or the inflection of a syllable.
For instance, "cacacaca" can mean either "hurry up" or "extreme diarrhea" from which the children of the Congo die.
There are other differences between the cultures, but obviously, the biggest hurdle is the language barrier. In a language so rich with meaning, miscommunications happen often which spell tragedy in both personal and governmental relationships.
