This has been one of my favorite poems since I first read it in high school.
When I was one-and-twenty I heard a wise man say, ‘Give crowns and pounds and guineas But not your heart away; Give pearls away and rubies But keep your fancy free.’ But I was one-and-twenty, No use to talk to me. When I was one-and-twenty I heard him say again, ‘The heart out of the bosom Was never given in vain; ‘Tis paid with sighs a plenty And sold for endless rue.’ And I am two-and-twenty, And oh, ’tis true, ’tis true.
A Shropshire Lad: XIII – A.E. Housman, 1896
