" 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. "

― Charles Dickens , David Copperfield
