It was clear from the start that Sylvie is not the most responsible adult. In chapter 4, Ruth and Lucille have to lie to Lilly and Nona about Sylvie telling them to come inside and not play in the snow, when in actuality the roles were reversed and Sylvie was the one outside in the snow without protection from the elements. The fact that Ruth and Lucille lied about this right off the bat after barely knowing Sylvie at all is very significant, because it was as if they knew Sylvie wan't going to become more responsible, and they wouldn't come across any real stories of Sylvie in that take-charge role.
I guess it makes sense, though, that Ruth and Lucille developed such strong feeling towards Sylvie; they had been abandoned by Helen when she committed suicide, they were "abandoned" by Grandma Sylvia when she died, and they were basically straight up abandoned by Lilly and Nona, who couldn't wait to get away. Sylvie was he first person in a while who was actually nice to the girls, even if she wasn't the best role model.
My last blog post was about it isn't inherently bad that Sylvie is a transient (or at least that's what I was trying to say; I hope that the point got across) so I almost just beat myself up for saying that Sylvie isn't a good role model. However, she isn't the best role model. It's not the fact that Sylvie isn't good at keeping put any adjusting to life in a house that makes her bad role model, it's the fact that Sylvie does not know how to act socially. I don't like the way I'm phrasing that, but the only other words that came to my head were about Sylvie not being able to follow the rules of society, and yet that sounds very conformist and I don't mean it to.
The thing is, Sylvie just straight up stole a mans boat in chapter 8 (I think) with Ruth at her side, and she completely ignored the fact that she just stole a dudes boat. I don't think that's okay. There's also the fact the they stole this boat to go visit some ruins when Ruth was supposed to be in school. Sylvie actually persuaded Ruth to skip so they could go on this adventure, and I don't think that's good because I believe people should have at least a basic education, and having your guardian persuade you to skip isn't exactly the best way to guarantee that happens. Additionally, I feel like Sylvie definitely should have called the police after Lucille ran away, no matter how much she didn't want to; something bad could have happened to Lucille and it was irresponsible of Sylvie to not do everything she could to locate her.
