3rd paragraph, second sentence; “…reminding him of switches he was sent…”?
It is interesting that he is in a place where it appears there is no chance of smelling much of anything (desolation), and that all of his memories are based on smells. It is easy to forget that some of our strongest memories come from smell. Great little story.
Lyrical and quite beautiful. “…of switches he was sent” sounds fine to me, so not sure why the query in the previous comment, unless I’ve missed something.
