Love's Paradox

Once I smiled when I saw you, when I saw you smile I was glad,
And the joy of my heart was as foam that the sea-wind shakes from the sea;
But the smile of your eyes grows strange, and the smile that my lips have had
Trembles back to my heart, and my heart trembles in me.
 
Once you laughed when you met me, when you met me your voice was gay
As the voice of a bird in the dawn of the day on a sunshiny tree;
But the sound of your voice grows strange, and the words that you do not say
Thrill from your heart to mine, and my heart trembles in me.
