Word of the day: Peripety - a sudden change in a course of events

A boy stands at the edge of the water. He wears a plastic bag over his head,
it's sealed at the neck. He thinks he'll be able to breathe underwater;
he's wrong. He will drown when he jumps; he cannot swim.

I have long wondered if we sleep at night because it is too dark to hunt or gather.

I'm stuck in the city but I belong in a field.
