Classic Poem

Why blame the pranks that love does ever play?
What though my eyes be wet, my temples gray?
These cares are but the signs of passion's fire,
Of sleepless nights and unfulfilled desire,
Only the flame within me freshly burns,
All else to age and feebleness returns.
Yet though my sides are wrinkled in their prime,
My neck all loose and slack before its time,
If thou, dear heart, to love me now will deign
I shall grow young, my hair turn black again.
