The shifts of fortune test the reliability of friends.

Friendship with oneself is all-important, because without it one cannot be friends with anyone else.

You are my best friend as well as my lover, and I do not know which side of you I enjoy the most. I treasure each side, just as I have treasured our life together.

Friendship is a single soul dwelling in two bodies.

A doubtful friend is worse than a certain enemy. Let a man be one thing or the other, and we then know how to meet him.

Betray a friend, and you'll often find you have ruined yourself.
