Would changing how a first person character refers to another character be an effective way to show that their attitude has changed toward that person? Would it be confusing to the reader? For example, in the beginning of the story, the MC refuses to call her mother's parents anything but "my mother's parents" or "the Smiths" because she has never met them and is angry and hurt that they didn't want to raiser her after her mother died (her father was already dead). Later in the story, when the MCfinally meets them, she gets to know them and softens her heart toward them. That's when she would start referring to her has "my grandparents". I was thinking that changing how she refers to them would reflect and reinforce her change in attitude toward them. Does this make sense to any one but me?
