" Her face… is without expression. But what should it express in the moments when nothing speaks to her heart? … she does not have… that falseness which sometimes seduces, but invariably deceives. She does not know how to disguise an empty phrase with a studied smile… Though she has the most beautiful teeth in the world, she only laughs at what she finds truly amusing… You should see what a picture of naive … gaiety she sees when we play games; her look of pure joy, goodness and compassion when she is near some poor wretch she is anxious to help "
