I'd hang out with

Caroline. She seems like the epitome of chill and that's my happy place. It'd be a kind of weird town with only Caroline in it but since I couldn't tell if anyone else existed, I'd probably assume she was the only one. Just to keep things simple of course.
Maybe when Caroline needed to go somewhere, like take a nap or whatever I might notice that

Maru wandered into this ghost town and it would totally be fun chatting science and astronomy and engineering and those things.
It would be weird if they mentioned anyone else because then I'd be wondering like, where are these everyones hiding? Maybe I'm too scaryfarmer for them.
Or
Maybe I smell.
Oh. Yeah it's probably because I smell. Well Caroline's olfactory system is blown out by excessive intake of only moderately governmentally regulated substances and it's very likely Maru's nose is so slathered in machine oil that to her the entire world smells like an automaton's lavatory.
It's important to choose your friends wisely.
