We say 'forest' but this word is made of the unknown, the unfamiliar, the unencompassed. The earth. Clods of dirt. Pebbles. On a clear day you rest among ordinary, everyday things that have been familiar to you since childhood, grass, bushes, a dog (or a cat), a chair, but that changes when you realize that every object is an enormous army, an inexhaustible swarm.
