Man is respecter of nature. Without being prodded, he knows the right thing to do and the reason he oversees the creation of the Creator.
The law of creation demands that man must procreate and it is the woman that must undergo the process. Being so compassionate, nature stipulates that the woman must take a maternity leave to regain her strength and nurture the child for a certain period. Because it takes two to tango, should a man also take a paternity leave to stay with the wife and nurture the newborn too?
