Boat

"That life had been one without excitement, with no adventure. It had been too safe. All the elements that made it up were right there before his eyes, and nothing new could ever be expected. It was like, he had once thought, a little plastic boat that would sail on forever, without incident, until it finally sank, which would be a secret relief to all."
--Philip K. Dick,
"A Scanner Darkly" (1977)
