Have never used the jealous trait as am a bit lazy with maintaining relationships in my game, nor do I use 'bro'.
I also haven't used kleptomaniac very often, though amusingly I get a lot of townies with the klepto and/ or evil traits.
My favourite traits are erratic and paranoid because I like their random reactions. Glutton makes for some good comedy photos. I like childish too as it's fun to watch them playing with the big stuffed animals. ?
