Joan Didion said this quote

This was an adequate enough performance, as improvisations go. The only problem was that my entire education, everything I had ever been told or had told myself, insisted that the production was never meant to be improvised: I was supposed to have a script, and had mislaid it. I was supposed to hear cues, and no longer did. I was mean to know the plot, but all I knew was what I saw: flash pictures in variable sequence, images with no meaning beyond their temporary arrangement, not a movie but a cutting-room experience. In what would probably be the middle of my life I wanted still to believe in the narrative and in the narrative’s intelligibility, but to know that one could change the sense with every cut was to begin to perceive the experience as more electrical than ethical.
