Cute, smart & funny girl. Known to be loyal & to fight for those she loves. She trusts easily & gives unselfishly. Usually attracts liars, cheaters & users.
Rick's wife is so awesome. She is pretty & smart & would never cheat on him. She is a total Chasta. Too bad Rick is a cheating, lying jerk. She could do so much better.
