The difference between you and her 
(whom I to you did once prefer) 
Is clear enough to settle: 
She like a diamond shone, but you 
Shine like an early drop of dew 
Poised on a red rose petal. 
 
The dew-drop carries in its eye 
Mountain and forest, sea and sky, 
With every change of weather; 
Contrariwise, a diamond splits 
The prospect into idle bits 
That none can piece together.
Robert Graves
