Two Millay Sonnets

I shall forget you presently, my dear,
So make the most of this, your little day,
Your little month, your little half a year,
Ere I forget, or die, or move away,
And we are done forever; by and by
I shall forget you, as I said, but now,
If you entreat me with your loveliest lie
I will protest you with my favorite vow.
I would indeed that love were longer-lived,
And [vows]1 were not so brittle as they are,
But so it is, and nature has contrived
To struggle on without a break thus far, --
Whether or not we find what we are seeking
Is idle, biologically speaking. 

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 winter stands the lonely tree,
Nor knows what birds have vanished one by one,
Yet knows 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.
