Brun looks perfectly reasonable to me. She is answering the questions that are asked as truthfully as is possible. especially bearing in mind that the she can probably work out that the purpose of the questions is to confirm her valid existence and to contact her. Even if their systems don't reject "None" - technically, the MOST truthful responses - it obviously wouldn't satisfy the purpose of the questions.
And why would she think it would be a problem with Renee? Politeness might dictate that she should verify with Renee first, but Renee wasn't available, so a simple calculation (Renee would be upset if I hadn't done what she woke me up early to do, and might be upset if I user her contact information without explicit confirmation, but if she expects me to do this she implicitly confirms that I have permission to do what is necessary to complete it) leaves little doubt as to the right course of action.
Brun didn't know anything about insurance, and is probably used to people informing her of what actions she needs to take as Renee did last comic and Clinton did when he got the hotel, so I highly doubt she knows about post office forwarding (and who would try to contact her by mail for a job opening anyway? The point is to have a valid, googleable, permanently-existing address to verify she probably actually exists, isn't it?) or phone replacement. I mean, *I* didn't know anything about those until I read this thread. If it were me, and I had no money, I'd just assume it was bridge-camping until a friend came back.
