What metaphors are used in Couldn't Keep It to Myself: Testimonies from Our Imprisoned Sisters by Wally Lamb?

In the story, Orbitting Izzy, Nancy Whiteley and Isadore become unlikely friends. Isadore tip-toes around the office, and she crashes into things. Isadore beats around the bush, and Nancy chops the bushes down (a metaphor for Isadore's reluctance to deal with things head on versus Nancy's candor in every situation).
