Friendship is always a sweet responsibility, never an opportunity.

To like and dislike the same things, this is what makes a solid friendship.

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.

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

Caring for but never trying to own may be a further way to define friendship.

Friendship... is not something you learn in school. But if you haven't learned the meaning of friendship, you really haven't learned anything.

Am I not destroying my enemies when I make friends of them?

Never have a companion that casts you in the shade.

But friendship is the breathing rose, with sweets in every fold.

It is more shameful to distrust our friends than to be deceived by them.
