One trait I absolutely dislike, and will use cheats to get rid of it on my premade townies, and decided, with all the anti bullying campaigns going on, to stop letting my Sims live with the trait, is loser. I think it's not very nice to watch my poor Sims fail at life, and laugh for my own amusement, and post it on (any) Sims 3 forum, because that's just not nice. In real life, we are doing more than ever to keep people from letting others from bullying, so I decided to do my part, and prevent bullying in the Simulated World as well. Plus, I think it goes against what our younger forum members, are trying to be taught to do in grade school. Being out of high school, and working a RL job, I think not letting my poor Sims fail, and be bullied, by using testingcheatsenabled true: Shift+Click=Modify Traits for Active Sims, on the premade townies such as Sunset Valley's Dorie Hart and Gobias Koffi, is the right thing to do in the situation. Plus, stories on the forum, to make Loser Sims for comical purposes sets a bad example. Which is why I decided to stop, including with Charlie Sheen, because I like him, and the loser trait isn't very nice.
I do however like to use not very nice traits, to create and share Sims, and their stories, for fun, LOL entertainment, that is rated E for Everyone, which goes below the T for Teen rating. Like the grumpy man who hates kids, and like to scare them, so he decided to build a simbot to keep those pesky kids away.
