Both individual and group-related, there are, indoor and outdoor, all kinds of tasks to accomplish. Every child from an early age learns to take care of themselves. Toileting, clothing, organizing things, give and take necessities, cleaning, etc. The child wants it itself and later on can and does it so. But not everything that the child can do, does it likewise. After all, it decides self what he or she wants to do. What he or she don't like he just doesn't. But if the other don't like it either nothing happens. And then the manipulator / negotiator comes on screen: 'would you do this for me, than I will do this for you' or, 'do you get that from me'. Or, 'if you me or us let do that, then you get that', or,' I or we will do that for you'. And there you are with your reasonable and unreasonable considerations. Because, what at first may be a reasonable question or an attractive offer, may have disastrous consequences for yourself and/or others in the long term. Especially if it becomes a habit. And after that a culture. A culture with all sorts of tasks and castings for men and women, old and young, rich and poor, powerful and powerless and leaders and co-workers, who must bring and keep all this into line.
Structurally, another lets do something, in exchange for a reward, namely has as a consequence.
Because another lets do something in exchange for other pursuits, delivers one-sided experiences for both parties. In other words, to barter are many snags, before you know it, you've fallen into a unscrupulous trap. Therefore you would do better to negotiate with foresight and a righteous conscience.
Please know with whom you are negotiating. Its bad bargaining with egoists. How beautifully they may occur, and how many promises they do, eventually they have one goal, which delivers me the most.
In a yourself and others not damaging society, people, animals and nature can't be expressed in value, but their services.
