Growing up as a child in Nigeria, it is a “taboo”, a show of disrespect, a lack of manners (home training) to use your left-hand to give out things, collect or receive things, eat with etc especially if you do that with an older person…naim be say your own done be.
You’ll either get a physical reprimand (either a knock on your head or a smack on the body) or verbal one or maybe both because you used your left-hand that is no different from the right-hand oo.
So the question is what is the big deal with the left-hand that Nigerians have decided to discriminate it as if it is not a part of what God created.
Is it because of the salient believe that anything left is not “good” in the minds of Nigerians especially as it is said in the bible that “those on my left will be sent to hell and those on my right to heaven” (something like that)
Studies have shown that left-handed persons go through a lot to adjust to most of the gadgets produced in world dominated by right-handed humans.
In essence, there is no right or wrong hand. If you are left-handed, you are unique because you are a minority in a right-handed dominated world.
