Erin is high. Erin is strong. Bob is little. Bob is small. Alan is wealthy. Gary is sad. Gary is dull. If someone is not big then they are sad. If someone is not rough then they are smart. If someone is wealthy then they are nice. If someone is nice and not bad then they are kind. If someone is sad and not big then they are poor. If someone is little and small then they are bad. If someone is bad and not nice then they are dull. All smart people are quiet. 
Gary is quiet.
