Familiar Faces? Or a feeling of dread?

I'm sitting here
staring at a blank board.
In a room full of strangers,
feeling out of place.

Arriving a half an hour early
so I cannot be late.
The quiet drum of my music
sooths my nerves.

The familiarity of a pen
flowing across the paper.
Makes the shaking in my hand deminish.
I feel at home.

The growing voices of the strangers
halt my pen,
cut off my ideas
and bring me down to earth.

As the clock ticks on
I grow restless.
Waiting for the Prof.
I feel my stomach flip.

What if I can't do this?
What if I freeze?
I swallowing the growing lump in my throat
and shake the thoughts from my head.

It is my first lecture ever
with no familiar faces
aside from my companions
my paper and pen.
