The impulse for much writing is homesickness. You are trying to get back home, and in your writing you are invoking that home, so you are assuaging the homesickness.
Joan DidionWe were not having any fun, he had recently begun pointing out. I would take exception (didn't we do this, didn't we do that) but I had also known what he meant. He meant doing things not because we were expected to do them or had always done them or should do them but because we wanted to do them. He meant wanting. He meant living.
Joan DidionI was supposed to have a script, and had mislaid it. I was supposed to hear cues, and no longer did. I was meant 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.
