I feel like I read this in middle school, maybe, but forgot about it. Interesting, food-for-thought. What would you do, or not, if you thought you were the last person on earth, and then it turned out that you were not, but the other person was crazy. Kinda like the Twilight Zone where the guy is all alone and wants to read forever but his glasses break. I doubt that at 16, I would have had the presence of mind to plan as Ann does.
