Bad Day

I've just finished making up answers on my Science test.
It was bad.
I mean, very bad.

Climbing up the stairs from the First Floor to the Second, I am always reminded of First-Grade, and the smells of the cafeteria in the noses of hungry children. I suppose it's because the stairs are near the kitchen, but the smell is this:
A hot pan, buttered, sits on the stove, while a woman opens a cold can of corn, and dumps it into the pot, stirring and peppering, and humming to boot.
That is what the stairway smells like.

How do I feel inside?

Nervous. Anxious. Worried.

About the test, I imagine.

Suddenly, I realize I am very hungry.
