This made me think about depth perception and the story of the person who’d lived their whole life in the jungle and was taken out to a great plain. He asked what those small animals were. He was told they were elephants. He just laughed and said they were too small to be elephants. As the vehicle he was in drove closer to the elephants: as the elephants got bigger, so did the man’s eyes. I have an uncle who’s probably seen the ocean twice in his life: he’d probably think oil tankers were just small boats.
