«This is what I meant when I said to you just now that I 'knew'. I've known perfectly that you knew I took trouble for you; and that knowledge has been for me, and I seemed to see it was for you, as if there was something - I don't know what to call it! - between us. I mean something unusual and good - something not a bit horrid or vulgar.»
