I've lived here almost 19 years. I have Yoruba friends. My grade school was in Ikoyi,Lagos.
I go to the market.
I work in Lagos.
I still cannot communicate in clear cut Yoruba.
I'm not one tenth as coherent as this Oyibo.
It is a very big deal.
And I don't know the kind of places you go to or if you've ever been abroad, but everytime a Nigerian speaks a foreign language such as German, Chinese etc there is always that extra warmth and camaraderie from the owners of the language, why?
