I've used the Practice Make Perfect trait on one of my sims when they aged up to a teen; they were Lazy already and I wasn't quite sure what to give them, so I landed on this trait.
With the Scare Seeker Lot Challenges, I've have this on a couple of household's houses; the households that have ghosts in them.
Sticky Fingers Aspiration: I put this on my Kleptomaniac sim, Henry, as it's perfect for him.
Prowling Peepers Eyes: I've made two families where some of the family members have these eyes.
Grouch Trait, haven't used this trait, haven't have a sim who I wanted to have it....YET.
Ring of Growth Tattoo: Currently, I have not placed this on anyone, however I do have a sim in mind for it, just haven't put it on them.
