So I've decided to continue the Not So Berry challenge since I can play in SM now. I've realized after a while, that most of my Sims are so mean! The rose generation Sim would always want to start fights with others (I think she started one with her father while I wasn't watching) and now my grey generation Sim just loves to shout forbidden words at other Sims. She never did that as a child or teen, only when she aged up. Just now, I saw that her husband was pretty mad, and so I clicked on him and saw that their relationship bar was decayed. Not by a lot, but still. I stopped him just in time from insulting her mother. :D Also, now currently living in Brindleton Bay, my Sims are always queueing up an interaction to do a rude introduction to whatever animal is outside. I mean, what did they ever do to you? :( Gosh darn, this makes an interesting save for sure.

Do they have the hot headed trait?
I had a hot headed sim, his son was too and they would be having a nice conversation and without warning go into full blown fight mode.
Relationships plummeted very fast.
I had heard it was related to the trait and thought it was fixed but maybe not.
