If you've never read the novel, at this point, very early in the story, Esther Summerson is a young girl being raised by a very unpleasant godmother. Esther never knew her parents, and has only known unhappiness. She blames this state entirely on herself. Her only comfort is her doll, named Dolly.
"I went up to my room, and crept to bed, and laid my doll's cheek against mine wet with tears, and holding that solitary friend upon my bosom, cried myself to sleep. Imperfect as my understanding of my sorrow was, I knew that I had brought no joy at any time to anybody's heart and that I was to no one upon earth what Dolly was to me."
I mean, for Christ's sake, Dickens. Tear my heart out, why don't you?
