We don't have a lot of wilderness here in the south of England but I decided that its just a matter of scale. For a small insect, an ant maybe, this clump of moss, dried twigs and leaves could be a wilderness.
day 11 - home
I think that some small creature calls this crevice in the wall "home". There were acorns around the entrance and there seemed to be a small tunnel leading back into the wall. A safe place to rest and store food for the winter = home.
