Thus for my own part I have more than once been deceived by the person I love most and of whose love, above everyone else's, I have been most confident. So that I believe that it may be right to love and serve one person above all others, according to merit and worth, but never to trust so much in this tempting trap of friendship as to have cause to repent of it later on.

Baldassare Castiglione, 1478-1529
