What books, or parts of books, have brought you to tears?

For me, it would be Ch.19, the pivotal chapter, in Great Expectations by Charles Dickens.

I think it was because I empathized with Pip's mixed feelings about leaving home after years of suffering abuse from his sister. He felt exactly as I felt when I left home at the age of 18 after years of abuse from the Wicked Witch of West Hollywood (AKA my mother).
