The Nigerian Culture: Custom and Etiquette

Irrespective of all the negative publicity Nigeria is getting, I am proud to say I am a Nigerian. Yes I was born and bread in Nigeria, ''naija'' as my Warri people would say. Nigerians are outgoing and friendly generally.In Nigeria, Custom and tradition is very important and it is expected that the traditional etiquette are followed irrespective of your educational qualification.
                                                                                                                                                    Growing  up we experienced a lot of behaviours both formal and informal which were  acceptable norms.Here are a few of them:

(1) A handshake with a warm, welcoming smile is the most common form of greeting after which you must ask about the person's welfare.
(2) People like to be addressed by their academic, professional or honorific title and their surname.
(3)When greeting someone who is obviously much older, it is a sign of respect to bow the head or bend your knee.
(4) when  invited to dinner at someone’s house it is advisable to bring gifts  for the host as well as gifts for the children.
(5)In Nigeria we don't have a first name culture so always wait until invited before moving to a first-name basis.
(6) The infamous African time. Nigerians usually don't keep to time for any meeting though few enlightened ones are changing that attitude.
