I Am Not

I am not an eraser
Because when I make a mistake,
Traces of it are left behind
To haunt me.

I am not the color pink,
For I am unaffectionate
And I stray away from people.

I am not a glass half empty;
I see the reward at the end
Of every adventure
That lights up
Like a billion fireflies.

I am not an act of silence;
The thoughts in my head
Whirl around back and forth,
Day and night.
