Stairs

In the shadows by the wall 
The stairs go on forever 
They could be steel 
They could be stone 
They could even be paper 
Are they leading up or down? 
The stairs go on forever 
Crowds of people in confusion 
Are they moving in or out? 
Are they moving, are they still? 
The stairs go on forever 
People going up stairs 
People going down stairs 
Ascending people 
Descending people
