It’s the story of a guy who warns everyone of imminent danger and then vanishes into the frozen water. The facts get confused. Everyone remembers his story differently from the other, until the guy reappears but they now ignore him.
It’s all about perception, like riding a ship down a muddy canal on a rich fall day.
Truth be told, there is no content. That’s the thing. I know I should spend less time on my perverted stories and listening to Black Sabbath’s Snow Blind. Too many old comics too.
