You do quite well at convincing them of your normality:
You smile, and hold your tongue,
towing the line between quirky
and downright bizarre.
You play their game
and let them believe what they must
to sleep at night.

But in the depths of your soul,
You feel the thrumming heartbeat
        Of the universe—
                Its howls of agony
               And its music flowing through
                                               your veins.
Your heart hammers in your chest
           to the call of the stars.

You will follow it to the end of all things.
