"Spring is like a perhaps hand"

by e e cummings, poem found here

Spring is like a perhaps hand 
(which comes carefully 
out of Nowhere)arranging 
a window,into which people look(while 
people stare
arranging and changing placing 
carefully there a strange 
thing and a known thing here)and

changing everything carefully

spring is like a perhaps 
Hand in a window 
(carefully to 
and fro moving New and 
Old things,while 
people stare carefully 
moving a perhaps 
fraction of flower here placing 
an inch of air there)and

without breaking anything.
