From Leaves of Grass, by Walt Whitman:

Among the men and women the multitude,
I perceive one picking me out by secret and divine signs,
Acknowledging none else, not parent, wife, husband, brother, child, any nearer than I am,
Some are baffled, but that one is not — that one knows me.

Ah lover and perfect equal,
I meant that you should discover me so by faint indirections,
And I when I meet you mean to discover you by the like in you.
