There was a man who had two wives. The senior wife was called the Iyale while the junior wife was called the Iyawo. The senior wife, the Iyale was very mean to the Iyawo.
She made life very hard for the Iyawo such that the Iyawo never had enough food to feed her children or nice clothes to wear.
The nicer the Iyawo was, the meaner the Iyale became.
