where the door only opens one way

Dingy yellow lights
Illuminate drip patterned stains of pale yellow, gray, brown
On cold cement and cinder cream walls.
The smell that comes with wearing a pair of jeans 7 days too many permeates the air.
Clinking, chattering, and coughing next door.
But I am alone.
There is no window, no handle on my door.
And I stare at the ceiling. At the dingy yellow lights.
