A small thesis on interpretation

Animals help one another. It doesn’t always show
but if you go out while freshly fallen snow is on the ground
you will often be able to follow a trail. For instance
you may see the tiny traces of a running mouse.
A little further on perhaps you find another and bigger trail
cross the path of the mouse. Often now it will appear
that the larger animal has helped the smaller animal on its way
through the troublesome snow, since only the larger track
continues. The animals help one another like that.
