A Metaphor From a Dream

I am ready to speak in that moment.
I have all my materials prepared.
I see the questions asked to my classmates.
I know every answer, and can ace it.
I see the categories, and know most.
But, the "Endgame" category is hard.
I have all my notes and materials.
I am ready... for once in my short life.
It is my turn. But, the class now ended.
Don't know if I'll have the guts tomorrow.
Or, if there'll even be a tomorrow.
