Nora Ephron is at a private film screening. There are not enough seats for the crowd and more people keep arriving. The host suggests they double up and sit on laps. Nora observes all this with mounting frustration, finally she tells her friend Bob:
"It's really very simple. Someone should get some folding chairs and set them up in the aisles."
Bob looks at me. "Nora," he says, "we can't do everything."
My brain clears in an amazing way.
Nora. We can't do everything.
