Nigerians are know for their strong cultural background,when it comes to custom and tradition its never towed with.

Respecting elders is part of our societal norms whereby the daily greeting which seem to be a form of good wishes to an individual is taken as respect.


In Nigeria when the younger ones come in contact with an elderly person they tend to greet them in the local language or mother tongue,they might also use the general English language(good morning or otherwise).
