Answer:
The reader experiences a fuller portrait of the narrator than Dee, who only hears the narrator’s external expressions.
Step-by-step explanation:
In "everyday use" by Alice Walker, Dee listens only to what the speaker speaks and this gives Dee a cursory glimpse of what the narrator is describing. This is because the narrator does not describe to Dee everything the narrator is thinking, but the reader can read all the narrator's thoughts and this gives the reader a more complex view of the characters.
