Here we go, this is a biggun'.
Storytelling Socials. This has been my big WIP for over three months, I think. It's a mod that adds over 50 interactions to the game. Some of them are hyper-specific, others are broad and purposely crafted to fit all Sims. From enthusing about your relationship, roasting your friends, mocking unfamous Sims, and more, this mod has quite a lot.
The full list of interactions will be available soon and the mod will be ready for public release in maybe a month or two?
