Okay kiddo, let me explain what "emi omo eso" means. "Emi omo" means "I am the child of" and "eso" means "fortune". So when someone says "emi omo eso", they are telling others that they are fortunate children. It's like saying "I am lucky" or "I am blessed".
It's a way of expressing gratitude for the good things in their life. Just like how you might say "thank you" when someone gives you a present or does something nice for you, people might say "emi omo eso" to acknowledge the good things in their life that they're grateful for.
So whenever you hear someone say "emi omo eso", you can smile and know that they're feeling lucky and happy about their life.
