This is true amongst Nigerians, and its the air of unfriendliness that hangs around us. You can feel the hostility in most cases as you get around the town doing your business.
Try stopping your car on the road and attempt a careful 3 point turn you will get what I am talkin about.
Try leaving the line at the bank to the rest room and see what happens when you come back to the line.
Asking the trader at the market why you should pay more for something you bought just last week.
Pretend your car has broken down in the middle of traffic and you are trying to get the engine running again , in less than 1min you will hear your story being told by passers by.

commot that pure water for road.
You no go find driver?

you de craze, thunder fire you, Ashawo! etc are common everyday.

Can this trend be controlled or stopped?

how many other nationalities have you observed for you to conclude that this behaviour is ascribed to only Nigerians?

dominique, I can say several nationalities, at least in central and west Africa, and outside Africa too.
One thing you will notice outside Nigeria is that people are a lot more patient at least when they are out in public. In most cases people will make you feel comfortable, not embarrassed if you make an obvious mistake, instead of treat you as a fool they would be amused by your mistake and correct you or tell you its ok, it happens or just be silent and let you sort yourself out.
This is not what I see back home in Nigeria. People would most likely make you feel odd and mock you when you make a mistake. I dont want to mention surprising comments I heard sometime when a friend lost N50,000.00 in a bank after withdrawal and was trying to finish someother business in the bank.
I am not saying all Nigerians are rude but its very very common that you would get rude talk for instance if you knocked down a womans basin of oranges in the market by mistake. You possibly will get her yelling and cursing first.

It is what bad leadership has passed down to us. It wasn't like that in d 70's like my father told me. When u have hostile leaders, crafty, uncaring wicked evil, then followers would b hostile at no provocation, cos things hardly works in such rulership environment

NICE POINTS!About Nigerians i don't know for us.No be only us get bad leaders,no be only us poor,no be only us get different people and issues.but na only us dey hate ourselves pass others.the treat nigeria suffers is from within and from within the heart of a typical Nigerian.for me outside the leaders,the religious leaders,teachers and parents have failed this generation.you are siting examples on the road?go to nursery and primary school and see how that has trickled into the life and blood of anything Nigerian.hate thy neigbour with all thy heart,encourage nepotism .may God bring relief and change for the people inflicted with the cancer of thoughts parent share with the children,religious leaders spread and teachers express.
