Friendship without self-interest is one of the rare and beautiful things of life.

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

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

Friendship is certainly the finest balm for the pangs of disappointed love.

Men kick friendship around like a football, but it doesn't seem to crack. Women treat it like glass and it goes to pieces.

Friendship multiplies the good of life and divides the evil.

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

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

Depth of friendship does not depend on length of acquaintance.

Without wearing any mask we are conscious of, we have a special face for each friend.
