Lucy is a disciplinarian/authoritarian. This is one of the 3 basic parenting discipline styles. The parents using this style of discipline are usually very strict and are comfortable in giving corporal punishments if the rules that they set were broken. Children born in this kind of family have no freedom and they are not encouraged to speak what is on their mind.
An oxymoron is a word that contradicts itself. It means that there are two words next to each other and they are opposite in meaning. Such as Almost Always never or it's freezing hot!
