About common sense and the concept of time

"It’s not that they lack common sense, it’s just that their form of common sense is so totally different to say, the north European interpretation of what’s common sense.
Same thing with the concept of time. It’s just as totally different to mine as it can be. In Europe our concept of time is dictated by efficiency and methods of being so, like fixed timetables. In West Africa these things hardly exist. Many people don’t know when they’re born. Their mother’s might remember if it was before or after the harvest, but have no clue at what year. With seven children it’s hard to keep track on such things, especially since it doesn’t matter to them at all. Take a look in a West African passport and it will most probably say: born on the first of January, then the numbers of a possible year."
