Duuring thier disastrous vacation on the mountains, Violet admits that she wants to be "normal" like Titus and his firends. Why does she say this? What exactly is "normail" ?

I belive she says this because she is frustrated by the situation she is in and wishes she had either never gotten the FEED, or could get rid of it.

By being "normal" she refers to the fact that Titus and his friends all have had the feed since they were children and grew up in families that could provide them with pretty much anything they wanted.
