Twenty minutes to nine.

"Her watch had stopped at twenty minutes to nine, and that a clock in the room had stopped at twenty minutes to nine.
'Look at me,' said Miss Havisham. 'You are not afraid of a woman who has never seen the sun since you were born?'" (Dickens 77).

This is a perfect quote to show one moral or message that Great Expectations, and therefore Charles Dickens is trying to send. One of the things he says, over and over again, through this book, is how much one single moment can change ones life, so it is better to think before acting and not make rash decisions, as Pip does. This quote shows how one particular moment (twenty minutes to nine, to be exact) changed things intensely in Miss Havisham's life. Her bridegroom left her at the altar, changing the remainder of her entire life, as is shown by the fact that she hasn't "seen the sun" since Pip was born.
