Foreshadowing

Why does the loveliest flower have the sharpest thorn
so you had to pay the tariff of young flesh pierced and torn
by the most splendid ornament that you had ever worn
as he clasped you to the music of the saxophone and horn?
It’s been true each day you’ve lived, was true when you were born,
and your father brought fresh roses—your bedside to adorn.
And it will go on being true on that future morn
when roses will be carried by those saddened and forlorn
as they place your ashes where you’ve asked that they be borne:
back to that same rose bush that so long ago was shorn
of the roses that you carried when your wedding vows were sworn.

The prompt today is thorny.
