It is a question a lot of people, including yourself, ask you. What do you say?
Your name. Where you’re from. What you’ve studied. Where you work. And so on.
While this might suffice as an answer to the average nature of said question, none of it is explanatory of your core identity. I.e., your roots- who you are.
Seldom, for short moments of time, you feel like you belong. To the people around you. To the place where you are. To the world. To yourself.
It has nothing to do with where you are from, what religion you follow or what your parents do. It is much more abstract than that. Much less explainable.
It is when you are in touch with your roots.
It is when you are you.
When you are truly fulfilled in every sense.
