whenever i sit down to write something, the first thing i do is choose a character whose perspective on the situation i want to see the most. reasons may be different: because it'd be funny, because this character has the least info on the situation or sits in the weirdest place or has the most complicated relationship with other people in the room etc. whatever makes it the most fun for me to write is good.
anyway i'm currently writing a short story about a village haunted by an ancient being who has signed a contract to collect a soul of one guy in exchange for giving him a nice lil house for a few years (the housing market there is horrible). the obvious choice would be to write it from that guy's pov but it seemed boring to me, so i'm writing the entire (or almost entire) thing from the pov of the ancient being. the reader however has no idea who the narrator is for a big part of the story, cause the being also has a homoerotic tension with the guy it signed the contract with and behaves like a young person with a crush. if it had feet it would kick them and blush while imagining how their souls become one. it also eats neighborhood pets to get his attention sometimes but the guy's used to it.
