What lips my lips have kissed, and where, and why,
I have forgotten, and what arms have lain
Under my head till morning; but the rain
Is full of ghosts tonight, that tap and sigh
Upon the glass and listen for reply;
And in my heart there stirs a quiet pain
For unremembered lads that not again
Will turn to me at midnight with a cry.
Thus in the winter stands a lonely tree,
Nor knows what birds have vanished one by one,
Yet know its boughs more silent than before:
I cannot say what loves have come and gone;
I only know that summer sang in me
A little while, that in me sings no more.
—Sonnet XLIII by Edna St. Vincent Millay (1892-1950)
And you thought black moments of heartache were only for romance novels! This poem evokes such romantic melancholy, and anyone who's ever had their heart broken will recognize the palpable loneliness she describes. But don't be too sad for Edna, however; from all accounts, it sounds like she led a pretty fabulous life.
Has a poem ever summed up just what you were feeling at a certain time? Which one was it?
