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

Friends and good manners will carry you where money won't go.

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

Never make friends with people who are above or below you in status. Such friendships will never give you any happiness.

Think where man's glory most begins and ends, and say my glory was I had such friends.

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.

Never contract friendship with a man that is not better than thyself.

As iron sharpens iron, so a friend sharpens a friend.

A friend is someone who gives you total freedom to be yourself.
