“no one can mark the exact moment at which friendship becomes love.”

“No love, no friendship, can cross the path of our destiny without leaving some mark on it forever.”

“Friendship marks a life even more deeply than love. Love risks degenerating into obsession, friendship is never anything but sharing.”

“Confession can be good for the soul, but it can exact a heavy toll on friendships.”

“From the moment absurdity is recognized, it becomes a passion, the most harrowing of all. But whether or not one can live with one's passions, whether or not one can accept their law, which is to burn the heart they simultaneously exalt - that is the whole question.”

“I should like to have friends, I confess. I do not suppose I ever shall. But there have been moments when I have realized what friendship might be. Rare moments - but never forgotten. Friendship is a binding, as solemn as marriage. We take each other for life, through everything - forever. But it’s not enough to say we will do it. I think, myself, it is pride which makes friendship most difficult. To submit, to bow down to the other is not easy, but it must be done if one is to really understand the being of the other. Friendship isn’t merging. One doesn’t thereupon become a shadow and one remain a substance. Yet, it is terribly solemn - frightening, even.”
