When the territory is unpredictable, when your land is a forest, not a garden, when you find your resources in Chaos
there is more risk.
But sometimes the risk pays off, and sometimes you have surplus.
Your neighbor might not have had the same luck. You do not need the surplus. You give it away. It would go to waste otherwise.
Couldn't you have made money out of this? No. You could not have made a deal in advance, for you could not have predicted the surplus. Likewise, you do not want your neighbors to starve, for they too will give you their surplus.
O you my neighbor
My mind is a forest
My thoughts are a gift
