Teachers and children, have you all seen this girl? You see she is very young. It is my duty to tell you that this girl is a little liar. You must avoid her company, not play games with her, and shut her out from your conversation. Teachers, you must watch her; keep your eyes on her movements and punish her - this girl is a liar! This I learned from her aunt in whose house the girl lived as a daughter.

The half-hour ended, it was five o'clock; school was over and everybody went to tea. I left the stool, went into a corner, and sat down on the floor. It was dark. Now I am crying. I wanted to be so good and do so much at Lowood; I made so many friends. Already I had made some progress - that very morning the teacher told me that I was among the best pupils of my class and promised to teach me drawing, and let me learn French if I continued to make progress two months later.
