I never, ever give my Sims the Active Trait because I hate when Sims start doing push ups and sit ups out of no where. Are there any traits that you avoid giving your Sims and why?
As a family player: any of the traits that cause autonomous dollhouse smashing. My legacy gen 2 married a hot-headed sim, and there were times she'd wake up just to smash her daughter's dollhouse. I'd make her repair it immediately if I couldn't stop her in time. I really considered getting rid of her, but she was a good mother otherwise.
