From Leaves of Grass, by Walt Whitman:

Once I pass'd through a populous city imprinting my brain for future use with its shows, architecture, customs, traditions,
Yet now of all that city I remember only a woman I casually met there who detain'd me for love of me,
Day by day and night by night we were together -- all else has long been forgotten by me,
I remember I say only that woman who passionately clung to me,
Again we wander, we love, we separate again,
Again she holds me by the hand, I must not go,
I see her close beside me with silent lips sad and tremulous.
