Under the stern gaze of the summer moon 
my big sister, Juliet to Romeo,  
Cathy to her Heathcliff,  
slid each night on the porch's sloping roof 
down to Lovers' heaven  
below our bedroom window. 
 
Little sister hugged the secret  
into her midnight pillow,  
waited for the tap of stones on glass 
then flitted like a ghost to unlock doors 
and let big sister in  
from her illicit play. 
 
Now that romance has flowered,  
yielded fruit and withered all away,  
I wonder, does a ghostly 
tapping on the glass 
disturb the dreams of sleepers in that room 
whenever moonlight silvers trees and grass.
