how did Mary's real feelings compare with her behavior as she listened to Mrs. Medlock and what did Mary's words lead Mrs. Medlock to say Mary is like

Mary's real feelings during her conversation with Mrs. Medlock seemed to be guarded and skeptical. While she appeared to be listening attentively, her behavior was somewhat aloof and distant.

Mrs. Medlock seemed to pick up on Mary's detached demeanor and commented that she was like a "little princess" who had been spoiled and left to do whatever she pleased. This comparison suggests that Mrs. Medlock perceived Mary as someone who had been given free rein to act as she pleased, without much structure or discipline.
