OK, thank you. So, just temporary unhappiness then. Good, 'cause I then misinterpreted Dennis's thoughts about his wife's baby a while back because he had a ton of red "x"s over the baby's face when he was writing in his diary one day, and I thought it meant he hated her/resented her because she isn't his. It's just that sometimes one Sim will walk past another (I've noticed it the most with the maid while she's working) and a bubble will pop up and sometimes has a red "x" over the person's face. I've never seen the fire-filled bubble though.
I've never had anyone steal the newspapers either, just pick it up, read it, and then put it back down again. Once, someone did kick over the Razaar's garbage can, though. I was surprised because I didn't think he even knew the family. That was a weird one.
