Sounds like a creative joke but can be true tho,but if such will happen how old was her son when the husband died?
Folks, this is one of the worst sections of culture.I've think over it again and again then came to a conclusion that this CANNOT BE TRUE.
Though any wrong doing that goes around in a community over a year will definitely become culture likewise the right ones.
Looking at it from the other side of life-as the culture implies, The woman might chose her son cos... she doesn't want some silly uncles that probably brought death to her husband to get on her for whatever silly culture they're practicing.
Guess the woman picked her son under arrangement while someone else she believes and would like to get along with stands aside cos... the culture didn't include him in the race.
BUT if knowing the woman pick her son and for what ever reasons they slept together, Oh my gosh! That's a death-role chain.
I beg May God forgive them, for they do not know what they're doing.It's totally WRONG.
Peace!
