I know it's May, but...

The Rainbow comes and goes,
And lovely is the Rose,
The Moon doth with delight
Look round her when the heavens are bare,
Waters on a starry night
Are beautiful and fair;
The sunshine is a glorious birth;
But yet I know, where'er I go,
That there hath past away a glory from the earth.
--William Wordsworth (1770-1850), Ode: Intimations of Immortality
from Recollections of Early Childhood

I enjoyed this poem so much, I couldn't resist.
