@puzzlezaddict I like the idea of a loyal trait. However, I have seen that kind of behavior in one household I played on high free will, which I don't normally do. The mother was mean-spirited and disliked children. She and her family oriented husband, who was a doctor, had five children, three girls and two boys. The oldest daughter had all good traits, but the two younger daughters were both evil. By the time the youngest daughter was born, the oldest was a teen. Since the father was not home consistently, and the mother was in the military and had to leave for work early, the oldest daughter took care of the youngest more than either parent did. By the time the youngest was a child, she and her big sister had a 100% positive relationship.
The mother and both younger daughters, due to the evil and mean-spirited traits, liked to sneak up on other family members and scare them. Every time the mother or the middle sister scared the oldest sister, the youngest sister would scare them, but she never, ever scared her oldest sister. So it seemed like she was getting even with anybody who was mean to her oldest sister, and always treating her better than she treated everyone else.
Regarding the inappropriate trait, that same youngest, evil daughter married a man with the inappropriate trait. He did flirt with other women, quite a bit, and went beyond just flirting besides. He had a cheater reputation in less than one sim week after they married.
