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

Real friendship, like real poetry, is extremely rare - and precious as a pearl.

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

Let there be no purpose in friendship save the deepening of the spirit.

Don't walk behind me I may not lead. Don't walk in front of me I may not follow. Just walk beside me and be my friend.

The language of friendship is not words but meanings.

An excellent man he has no enemies and none of his friends like him.

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

True friendship can afford true knowledge. It does not depend on darkness and ignorance.

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