Book XXIV: Autumn Rivulets - To a Common Prostitute

Be composed—be at ease with me—I am Walt Whitman, liberal and
        lusty as Nature,
Not till the sun excludes you do I exclude you,
Not till the waters refuse to glisten for you and the leaves to
        rustle for you, do my words refuse to glisten and rustle for you.

My girl I appoint with you an appointment, and I charge you that you
        make preparation to be worthy to meet me,
And I charge you that you be patient and perfect till I come.

Till then I salute you with a significant look that you do not forget me.
