The only reason she would think she's not supposed to is if we instill our beliefs on her, But it's just that, our beliefs, whether it's him, me, you, or goblins, she's going to form her opinion, at least at first, based on her environment, and then make up her own mind as she matures. She's getting to the point now where Araavos, is letting her make up her own mind about how she feels, he just doesn't put a limit on it like others would. While I don't completely agree with it, shouldn't we be happy that whatever she can dream of, however she feels, she's free to have it?
