This is the air; that is the glorious sun.
This pearl she gave me, I do feel ‘t and see ‘t.
And though ’tis wonder that enwraps me thus,
Yet ’tis not madness. Where’s Antonio, then?
I could not find him at the Elephant.
Yet there he was; and there I found this credit,
That he did range the town to seek me out.
His counsel now might do me golden service.

– William Shakespeare

Twelfth Night, Act 4, Scene 3. In Sebastian’s monologue, he tries to make sense of Olivia’s love for him. He treasures his new found love as a pearl and assures himself that he is not mad. But he wishes Antonio was around to give him some golden advice about his new girlfriend.
