It is a mouse no more. I forbid her go, and she raises up her chin like the daughter of a prince and lays to me, "I must go to Salem, Goody Proctor; I am an official of the court!"
– Arthur Miller
The Crucible, Act 2. Elizabeth Proctor is talking about the transformation in her servant Mary Warren. Her husband John has questioned why a mouse like Mary would frighten his wife. Elizabeth uses a "mouse" metaphor and "like the daughter of a prince" simile to describe how the once submissive Mary has become more assertive after working with Abigail and the other girls in the witch trials. This speaks to the theme of power, something the teenage Mary has now acquired because of her new status in court.
