The grandchildren are thought of as the grandparent's parents who have been reincarnated. Therefore, as children, they occupy the same position as the grandparents, but a little higher than the grandparents because they are supposed to be their seniors. However, the older a child becomes the more he takes on his own identity and the further he becomes removed from the position of seniority. When he becomes an adult, he occupies a position of less respect or honor.
And seniority is a really big deal.
A Gbande proverb: "He who is wise is one who listens to his wives."
