Child, I will give you rings to wear, 
And, if you love them, dainty dresses, 
Flowers for your bosom and your hair, 
And, if you love them, fond caresses; 
  
And I will give you of my days, 
And I will leave, when you require it, 
My dreams, my books, my wonted ways, 
Content if only you desire it. 
  
Love's captive, now his fugitive, 
All this I give you, for my part. 
I ask but what I cannot give, 
I ask no more than this: your heart.
Arthur Symons
