True friendship ought never to conceal what it thinks.

In friendship as well as love, ignorance very often contributes more to our happiness than knowledge.

Fear makes strangers of people who would be friends.

I have friends in overalls whose friendship I would not swap for the favor of the kings of the world.

Friendship is the shadow of the evening, which increases with the setting sun of life.

Sweet is the memory of distant friends! Like the mellow rays of the departing sun, it falls tenderly, yet sadly, on the heart.

Friendship is unnecessary, like philosophy, like art... It has no survival value rather it is one of those things that give value to survival.

Friendship may, and often does, grow into love, but love never subsides into friendship.

I don't need a friend who changes when I change and who nods when I nod my shadow does that much better.

Instead of loving your enemies - treat your friends a little better.
