learned by heart

Close close all night 

the lovers keep. 

They turn together 

in their sleep, 

 

close as two pages 

in a book 

that read each other 

in the dark. 

 

Each knows all 

the other knows, 

learned by heart 

from head to toes. 

 

[Elizabeth Bishop {1911-1979} 'Close close all night', from Poems, Prose, and Letters]
