Kin to Sorrow

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!
