Who are we if not indefinite?

What makes a young mind wander
Yes, that’s the question I ponder
Yes, that is the question we ponder
No, not our physique or appearances
But what may lead to our seemingly unquestionable disappearances
What keeps us lying awake every night
How do we solve the inquiry that fill our dreams with fright
Our world may be shaping to be dim and small
Our lives in comparison only a protocol
But alas, the future is nothing but a distant yonder
