L’esprit de l’Escalier

Stairs - 
eventual instruments 
of our declivity
for conveyance

drawing out 
validation
from body 
and will 

at each 
plane,
until 

the dangerous collapse 
  of one
 on to the other


L’esprit de l’Escalier - "stairway wit," a phrase describing the witticisms which arise after their window for delivery have expired (i.e. as you're going down a set of stairs).
