Well there's this girl I've been talking to and she doesn't understand the concept. She now believes in relativity, but she believes that because ideas and morals are relative, what is wrong to her isn't necessarily wrong to someone else and because there is no absolute way to decide what is right or wrong, there can't be any right or wrong.
She fails to understand that the universe technically doesn't have a right or wrong, everything is balanced, the concept of "right" and "wrong" is simply something created by life, therefore it is also defined by life. Life defines what is right and wrong by believing what is right and wrong and enforcing that the people who do the wrong things get punished and the people who do the right things don't. In society, majority rules and what the majority thinks is right is what will be right, if you disagree you can attempt to convince the majority to be on your side.
She still believes that because there's no universal right or wrong, she can't believe anything, I understand where she's coming from but she just doesn't seem to understand the concept

Ah well, maybe in some time haha.
