Carl Sandburg
Under the Harvest Moon

Under the harvest moon,
When the soft silver
Drips shimmering
Over garden nights,
Death, the gray mocker,
Comes and whispers to you
As a beautiful friend
Who remembers.
Under the summer roses
When the flagrant crimson
Lurks in the dusk
Of the wild red leaves,
Love, with little hands
,Comes and touches you
With a thousand memories,
And asks youBeautiful, unanswerable questions.

This poem talks about how beautiful life is, because there are moments in life when you have the chance to reflect on everything. When you remember life you realize how much you love it and how exctting it is to figure out what's next.

Death is the metaphore of a beautiful friend. Love comes to you as memories touching your face. Unanswered questions is a metaphore for the life that is still left to live.
