I have a love-hate relationship with Nancy Landgraab. I cannot stand her, I even gave her a make-over that made her look like the typical gold digger woman (bleached blonde, pink and white and lots of gold accessoires) and yet in some way I also love her in an "It's so bad it's almost good" way. She ticks me off every time I see her and I make my sims purposefully have a bad relationship with her because I just love to hate her. The same goes for the Calientes, I gave them short-haired chihuahuas (I can't stand them) because I hate the household but I love them as well because they bring drama to everything.
I hate those sims, but I also really really love them. Do you have a sim that you feel like that about?
