Your five year old son is your instructor; at ten your slave; at fifteen your equal and after that either friend or foe.
Your best friend is yourself.
You'll realize he was a friend when you lose him and see him no more.
You can't jest an enemy into a friend, but you can jest a friend into an enemy.
With a friend behind you, you have a safe bridge.
Wish thy friend joy of his journey, but pray in secret that he have no joy, for then may he return quickly to thee.
Who seeks a faultless friend remains friendless.
Who lends to a friend loses doubly.
Who ceases to be a friend never was one.
