If I had loved you, soon, ah, soon I had lost you.
Had I been kind you had kissed me and gone your faithless way.
The kiss that I would not give is the kiss that your lips are holding:
Now you are mine forever, because of all I have cost you.

You think that you are free and have given over your sighing,
You think that from my coldness your love has flown away:
But mine are the hands you shall dream that your own are holding,
And mine is the face you shall look for when you are dying.

When April bends above me
And finds me fast asleep,
Dust need not keep the secret
A live heart died to keep.

When April tells the thrushes,
The meadow-larks will know,
And pipe the three words lightly
To all the winds that blow.

Above his roof the swallows,
In notes like far-blown rain,
Will tell the little sparrow
Beside his window-pane.

O sparrow, little sparrow,
When I am fast asleep,
Then tell my love the secret
That I have died to keep.

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 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.
