Prompt 4: Tell me why they keep so few friends (or can’t keep any friends).
Maybe trust issues? Maybe they just don’t like people? Introvert? Or maybe they aren’t even human or humanoid and are a wild animal who wants to be alone? 
Mine:
In Alive At Crepusculum, Richard doesn’t keep many friends. Being a psychopath, it’s difficult for him to understand what friendship means for non-psychopaths. He does have a few people he gets along with, but even if they would say “Richard, we have each other’s backs and that makes us friends”, he wouldn’t understand how “have each other’s backs” is linked to “friends”.
It might sound selfish to the rest of us, but he sees friends as “particularly enjoyable to be around compared to others because they are useful and they don’t get in the way of my goals and sometimes are willing to help me achieve them”. This isn’t him consciously being mean or standoffish or manipulative (although he can do these things consciously). He just sees friendships in a different way.
Because of the differences with how he sees friends and how others see friends, not many people stay in Richard’s life unless they are willing to feel not so good all the time when being around him. So, he’s only able to keep a few.
I did a lot of research on how a psychopath really thinks and how being a psychopath doesn’t automatically make the person evil. Richard is not trying to be mean to his friends. However, this doesn’t justify his murderous actions which are completely separate from him being a psychopath. And he can most definitely copy how others are “being a good friend” to blend in and keep his friends (which he sees as useful but not in a consciously manipulative way although he can also be manipulative).
Tricky stuff to write.
