A. Brutal working conditions
I predict that this person is connected with nature, at first it sounded like they were on drugs, but nearing the end it made the person connect with nature and other souls, I also predict that she is talking about spirit animals or the way they are related to her. Hope this helped!
Given that 'blunt' means 'not smart' and that 'mettle' means 'wit; intelligence', I believe that the statement that best paraphrases "What a blunt fellow is this grown to be! He was quick mettle when he went to school" is "This man, who was smart in school, has grown up to be unintelligent".
