The Apocalyptic Terrarium Challenge

Erratic Sims talk to themselves. Loner Sims need less social interaction. There are reward traits that slow social decay. When necessary for my story, I cheat in extra CAS and reward traits. You can talk to plants. I think you might be able to talk to a guitar. I am not sure all the ways that a sim can raise their social needs. children can talk to toys and stuffed animals, but I don't know about adults.
