Teacher and pupil were both very strong-willed and frequently clashed. One of the first of these battles revolved around Helen's behavior at the dinner table, where she roamed freely and grabbed food from the plates of others. Dismissing the family from the room, Annie locked herself in with Helen. Hours of struggle ensued, during which Annie insisted Helen eat with a spoon and sit in her chair.

In order to distance Helen from her parents, who gave in to her every demand, Annie proposed that she and Helen move out of the house temporarily. They spent about two weeks in the "annex," a small house on the Keller property. Annie knew that if she could teach Helen self-control, Helen would be more receptive to learning.
