Somali naming

Somali naming usually goes like this. Your first name, your father's first name and your grandfather's first name. For instance, Khadar (my first name), Muktar (my father's first name) and Osman (my grandfather's first name). And this is why I was saying when you call out for a somali person, always call out their first name. They are more likely to respond to that. And I feel like last names are a way of identifying yourself. But in everyday life, FIRST NAMES are more important then last names.
