“Friendship may, and often does, grow into love, but love never subsides into friendship.”
Quoted by Marguerite Gardiner, Countess of Blessington in Conversations of Lord Byron with the Countess of Blessington http://books.google.com/books?id=w648AAAAYAAJ&q="Friendship+may+and+often+does+grow+into+love+but+love+never+subsides+into+friendship"&pg=PA179#v=onepage (1834).
“Love is not always evil, truth to tell;
Though harm he does, he serves the good as well.”
Dunque Amor sempre rio non si ritrova:
Se spesso nuoce, anco talvolta giova.
Canto XXV, stanza 2 (tr. B. Reynolds)
