I agree - my sims couple both got close knit - they were best friends with another couple so all was good, but then just accidently getting friends from being out - they both got very strong tense moodlets for having too many friends - the only way to get rid of it was to actually use mean interactions on the accidental friendships until they went down to acquaintances! I then realized they counted family members so if they have children - they will be tense constantly and lose the close knit eventually. And what of a family that has many children - they would either never be able to get close knit or they would have to not like some of their children or each other!
