Chimamanda Ngozi Adichie said this quote

Mama had greeted him the traditional way that women were supposed to, bending low and offering him her back so that he would pat it with his fan made of the soft, straw-colored tail of an animal. Back home that night, Papa told Mama that it was sinful. You did not bow to another human being. It was an ungodly tradition, bowing to an Igwe. So, a few days later, when we went to see the bishop at Awka, I did not kneel to kiss his ring. I wanted to make Papa proud. But Papa yanked my ear in the car and said I did not have the spirit of discernment: the bishop was a man of God; the Igwe was merely a traditional ruler.
