In Africa, greeting is not optional, though it varies from place to place and from one culture to another. The African tradition demands that younger people do forms of greeting that shows they recognize the elderly among them, and in turn, the elders respond in an impressive way to express their acceptance to the loyalty pledged by the younger ones.
In Yoruba for instance, people prostrate on the floor as an act of greeting and remain there until they are asked to stand up. In other parts of Nigeria like the East and North, greetings are made categorically clear to those who deserve them. And so it is in other parts of African Countries.
Merely saying hi to people who should be properly greeted is one of the menacing borrowed cultures of the Western World that is evasively pushing the valued tradition of the Africans to the side.
Many Africans who associated with the Western World for a long time find it difficult to adjust to what is seen as a norm here in Africa. There are unbelievable instances of children coming back from the west to Africa to address their parents as Hommie, Nigga, and Old boy and lots more. It is emphatically wrong for a culture to borrow another culture that will wipe away its values, rather, a culture should borrow cultures that will compliment it’s effort to be better.
Finally there is no civilization with being disrespectful. Trying to do a “kissy kissy” kind of greetings like France people or a weighty handshake in Sierra Leone will never replace the form of greeting that the African people have long been known for.
African culture is rich in all sense, to promote the African tradition and culture means to uphold it proudly when-and-where ever.
