Quote from David Copperfield, end of Chapter 14.

As the bus passes through Dickens, Texas Florence closes the curtain to the window.  The window that faces the wild land she is now leaving.

"Thus I began my new life, in a new name, and with everything new about me.  Now that the state of doubt was over, I felt, for many days, like one in a dream.  I never thought that I had a curious couple of guardians, in my aunt and Mr. Dick.  I never thought of anything about myself, distinctly.  The two things clearest in my mind were, that a remoteness had come upon the old Blunderstone life - which seemed to lie in the haze of an immeasurable distance; and that a curtain had for ever fallen on my life at Murdstone and Grinby's.  No one has ever raised that curtain since. I have lifted it for a moment, even in this narrative, with a reluctant hand, and dropped it gladly.  The remembrance of that life is fraught with so much pain to me, with so much mental suffering and want of hope, that I have never had the courage even to examine how long I was doomed to lead it.  Whether it lasted for a year, or more, or less, I do not know.  I only know that it was, and ceased to be; and that I have written, and there I leave it."
