What should ancient young people call themselves in front of their elders?

You can call yourself a nephew in front of your uncles, aunts and other elders. Call yourself grandson and baby in front of my grandparents. Call yourself brother in front of your brother and sister-in-law.

You can be called a late student in front of a scholar who is not your elder, boy.

In front of officials, you can call yourself the next official, villain. I am also an official, calling myself the next official.
