And then let's be frank, Lee, how long can you look at a sunset? Who wants a sunset to last? Who wants perfect temperature? Who wants air smelling good always? So after awhile, who would notice? Better, for a minute or two, a sunset. After that, let's have something else. People are like that, Lee. How could you forget?"
"Did I?"
"Sunsets we always liked because they only happen once and go away."

Ray Bradbury, Dandelion Wine
