Thou Art But Young, Thou Say-st

Thou art but young, thou say-st,
And love-s delight thou weigh-st not.
Oh! take time while thou may-st,
Lest, when thou would-st, thou may-st not.
If love shall then assail thee,
A double, double anguish will torment thee.
And thou wilt wish, but wishes all will fail thee.
Oh! me that I were young again! And so repent thee.
