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

Nothing so fortifies a friendship as a belief on the part of one friend that he is superior to the other.

Friendship is always a sweet responsibility, never an opportunity.

True friendship is like sound health the value of it is seldom known until it is lost.

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

Since there is nothing so well worth having as friends, never lose a chance to make them.

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

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

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

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.
