Not until you become a stranger to yourself Will you be able to make acquaintance with the Friend.
A good friend who points out mistakes and imperfections and rebukes evil is to be respected as if he reveals a secret of hidden treasure.
One of the surest evidences of friendship that one individual can display to another is telling him gently of a fault. If any other can excel it, it is listening to such a disclosure with gratitude, and amending the error.
Reprove your friends in secret, praise them openly.
A man cannot be said to succeed in this life who does not satisfy one friend.
Purchase not friends by gifts; when thou ceasest to give, such will cease to love.
Then come the wild weather, come sleet or come snow, We will stand by each other, however it blow.
Friendship requires deeds.
Never contract friendship with a man that is not better than thyself.
Be not the fourth friend of him who had three before and lost them.
