]Both were responsible for not giving their parents some information, but Jane would rather spare their parents. Much as I like Jane I have doubts with her sense here. Under stress perhaps or part of her nature to think this way?

Upon reading this part of the book, I always thought that Jane lacked sense (or she was just really dense and naive). To me it always seemed as if she wanted to think the best about everyone, and would rather live in her delusions of happiness rather than bring something like this out in the open. She knows how terrible he is, yet still wants to believe that he will marry Lydia when everyone knows that the chances are zilch. It makes me almost think that she is stupid to somehow miss how people truly are (such as Caroline Bingley). I don't think that stress effected her decision not to tell - I'm sure that she really did care about her parents and just wanted what was best, but still, why be glad that she spared her parents from hearing about Wickham when they ended up hearing about him in the end? In my opinion, I agree with Lizzy - no matter how hard it would have been for them to hear it, it would have been better that they know then and prevent Lydia from going off to Brighton than Jane's idea of trying to spare them grief when it would only bring them more - I don't see much sense in her logic here. (Hope that works as an answer)
