The Havamal.
"Repay gift with gift, repay guile with guile."
A man should be loyal through life to friends,
And return gift for gift, Laugh when they laugh,
but with lies repay A false friend who lies.
With a good man it is good to talk,
Make him your fast friend:
But waste no words on a witless oaf,
Nor sit with a senseless ape.
An evil man, if you make him your friend,
Will give you evil for good:
A good man, if you make him your friend"
Will praise you in every place,
Affection is mutual when men can open
All their heart to each other:
He whose words are always fair
Is untrue and not to be trusted.
Havamal goes on to mention that one should not consider people who are different than them a target for ridicule or discrimination (They're not saying all are created equal, just that no one is useless or incapable, thus are deserving of respect)
Not all sick men are utterly wretched:
Some are blessed with sons,
Some with friends,
some with riches,
Some with worthy works.
71.
The halt can manage a horse,
the handless a flock,
The deaf be a doughty fighter,
To be blind is better than to burn on a pyre:
There is nothing the dead can do.
It is always better to be alive,
The living can keep a cow.
And against passing judgements on another:
Never reproach the plight of another,
For it happens to many men:
Strong desire may stupefy heroes,
Dull the wits of the wise
Well, there you have it. The Havamal is an Ancient document that was passed on by word of mouth for a thousand or more years b4 being written down. Kind of a viking age Emily Post etiquette lesson (kind of a surprise, eh? Ndns weren't the only folk to be demonized and marginalised by the operating systems of the day.)
