Friendship, like the immortality of the soul, is too good to be believed.

A true friend is the greatest of all blessings, and that which we take the least care of all to acquire.

There are no rules for friendship. It must be left to itself. We cannot force it any more than love.

Be true to your work, your word, and your friend.

Even where friendship is concerned, it takes me a long time to trust people.

Silences make the real conversations between friends. Not the saying but the never needing to say is what counts.

That friendship will not continue to the end which is begun for an end.

You can always tell a real friend: when you've made a fool of yourself he doesn't feel you've done a permanent job.

Depth of friendship does not depend on length of acquaintance.
