In Act I, when Parris questions why Abigail was let go from her service at the Proctors' house, Abigail tells her uncle "They want slaves, not such as I." It is a lie; the Proctors have not overworked her or mistreated her, but Abigail is desperate to evade the truth about why not only the Proctors, but also other families, refuse to have her in their homes as a domestic servant.
Later in Act I, Abigail speaks harshly of Elizabeth Proctor when she is briefly alone with John Proctor, telling him:
She is blackening my name in the village! She is telling lies about me! She is a cold sniveling woman and you bend to her!
Abigail also tells John that she knows it is Elizabeth who fired her, not John.
In Act III, Abigail tells Danforth in the court that "Goody Proctor always kept poppets." This is another lie, but Abigail asserts it as truth to make her accusation against Elizabeth seem more credible. She knows that Mary Warren has taken a poppet to the Proctors' home, and Abigail is able to frame Elizabeth Proctor for witchcraft in this way.
