Nico had once read a story from Plato, who claimed that in the ancient times, all humans had been a combination of male and female. Each person had two heads, four arms, four legs. Supposedly, these combo-humans had been so powerful they made the gods uneasy, so Zeus split them in half - man and woman. Every since, humans felt incomplete. They spent their lives searching for their other halves.
And where does that leave me? Nico wondered.
It wasn't his favorite story.
