I don't understand why people cannot come out honestly to answer a simple question. And these people are precisely Nigerians.
Let's start with one's Date of Birth. I suppose everybody has one. So what's the big deal then in saying this if asked. You ask someone for his DOB, he says N/A. You ask someone for his age, he/she comes up with this ambiguous answer: "am over 20, 30, or 40" or it's "am nearer 40 to 30". Is that your age?.
You ask a Nigerian how many children she's got and the answer is "wọn kii ika ọmọ fun ọlọmọ" meaning you do not count other peoples children, or they tell you "I am blessed with both boys and girls". You innocently ask a Nigerian pregnant woman in the middle of a conversation: "when is the baby due?" and she gives you a vague answer: "very soon" - what date is that? sometimes some would stupidly say "am still not sure"! How can one not know her baby's due date? You cannot even ask some men what they do for a living! They dribble you and tell you sweet tales of nothing.
I don't understand this, why are Nigerians so evasive?
