I find the traits over all pretty pointless. But some of the negative ones do give me a chuckle now an again. One of my sims lives with his brother, sister-in-law and their baby. The Sim's mother comes over for a visit, he invites her in and they talk. Baby starts crying, I go to make sure someone takes care of it. When I come back to them the mother is leaving. I stare at the living room, something doesn't look right. Why is there so much space in the middle...Oh my god! The sim's mother is a klepto and she took the sofa. I never let her into the house again.
