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

Be courteous to all, but intimate with few, and let those few be well tried before you give them your confidence.

A true friend never gets in your way unless you happen to be going down.

Rejoicing in our joy, not suffering over our suffering, makes someone a friend.

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

There is some self-interest behind every friendship. There is no friendship without self-interests. This is a bitter truth.

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.

Friendship is something that creates equality and mutuality, not a reward for finding equality or a way of intensifying existing mutuality.

The sincere friends of this world are as ship lights in the stormiest of nights.
