@Chazzy my point was to avoid negative moodlets not add them. LOL. But I see what you mean, it might be taken both ways.
I know you can turn off emotional auras for objects but I don't think there is a way to turn off a Sim getting upset because the walls & floors aren't decorated enough. I think someone said it was because I had no wallpapers up & no flooring installed or something so my Sim got upset & it lasted hours.
Is there a cheat code to end a negative moodlet? I had forgotten to put wallpaper on 1 wall in the room & my Sim was mad about it for hours. LOL.
