Edna St. Vincent Millay - Kin to Sorrow lyrics

Am I kin to Sorrow,  That so oft Falls the knocker of my door—  Neither loud nor soft, But as long accustomed,  Under Sorrow's hand? Marigolds around the step  And rosemary stand, And then comes Sorrow—  And what does Sorrow care For the rosemary  Or the marigolds there? Am I kin to Sorrow?  Are we kin? That so oft upon my door—  *Oh, come in*!
