"Thank you. I think... that I would not do that, and, if I tried, I would not succeed, for many reasons. I think that my brother who is very very much better than I am at charming people still probably could not become most people's best friend in a week, and, even if he could, would not be a good enough seer to ask their futures things and get back answers he understood. I think that the best seer in the whole tribe, who I haven't met yet but I've seen a lot of in the future before I stopped having one, is mostly too busy averting lots and lots of doom to have any time for asking people questions in their futures that she can't ask yet in their presents, so I can't tell you if she would have been going to succeed at it because she wasn't going to try it, not even slightly. But the guess that I have is that you would notice, if she did that, because before she could find out what you would tell her if she spent a week becoming your best friend, she would need to spend several days tracing that path through the future so she could see what was at the end of it, which, I think, would make it harder for her to spend a week becoming your best friend. Which I am also separately not sure she could do to begin with, even if she planned very carefully."
