George Macdonald said this quote

But I never just quite liked that ryhme.''Why not, child?''Because it seems to say one's as good as another, or two new ones are better than one that's lost. . . . Somehow, when once you've looked into anybody's eyes, right deep down into them, I mean, nobody will do for that one any more. Nobody, ever so beautiful or so good, will make up for that one going out of sight.
