"I found in Thérèse the substitute that I needed. Thanks to her, I lived happily, as far as the course of events permitted. At first I tried to improve her mind, but my efforts were useless. Her mind is what Nature has made it; culture and teaching are without influence upon it. I am not ashamed to confess that she has never learnt how to read properly, although she can write fairly well."
