Comfort and conflict may seem distant cousins but generally comfort is the outcome of successful conflict for the consumer.
Some comforts are pre destined and arranged for animals and plants on this planet, the sun and rain, both essential elements for continuing their biological function. Sun and rain may be predestined but whether on not arranged is a side discussion of little importance.
It is difficult to find a non cyclic staring point and so I chose to to go for the arranged and preparations that biological consumers rely upon, and an individual must be the focus. Whether DNA, Foetus, Child or Parent is only important as to where to start, so choosing the middle way there is both the Foetus and The child.
Each has parents that will to some degree make special arrangements for the comfort and growth of their charge. Whereas the sun is pretty consistent however warmth is not and is the first object to be sought after for the child after birth, water being the second. Both of these are commonly provided by the custodian, initially by the mother in the mammalian arena.
As the child grows it, observing it's custodian, seeks it's own resources for comfort and except for the sun and the air the resources have to be acquired from a finite pool over which there is inevitably conflict as there is more that one consumer.
And so there is preparation for this conflict.
