WHEN YOU WERE SWEET SIXTEEN
When first I saw the lovelight in your eye,
And heard thy voice, like sweetest melody,
Speak words of love to my enraptur'd soul,
The world held naught but joy in store for me.
E'en though we're drifting down life's stream apart,
Your face I still can see in dream's domain;
I know that it would ease my breaking heart
To hold you in my arms just once again.
I love you as I never loved before
Since first I saw you on the village green,
Come to me, or my dream of love is o'er,
I love you as I loved you
When you were sweet,
When you were sweet sixteen.
